Converts the fxos8700 sensor driver to the new gpio api. Updates device
trees for all boards with this sensor to active low gpio interrupts by
default.
Tested on frdm_k64f and rv32m1_vega_ri5cy boards. The latter verifies
that the reset output works correctly.

Update ALERT active level in all devicetree files. Capture GPIO flags
in static configuration. Add internal API to enable and disable
interrupt, to release the handlers when an alert occurs, and to
re-enable the signal when the handler completes. Check for alerts
received during periods when the interrupt was disabled.
Extend the example to handle both above and below range triggers and
alerts that are present on startup.

The firmware version on the CCS811 on nrf52_pca20020 is generally
version 1.1, which does not set the data ready bit in the status
register. Assume that a non-zero CO2 measurement on that version is
fresh for the purposes of determining the fetch status.

The application may want to know the configured mode without inspecting
Kconfig macros; this is important for proper management of BASELINE
which is mode-dependent.
It also may need to know the version of the hardware and firmware, as
the behavior of application firmware 2.0 is significantly better than
version 1.1.

Expose the entire content of the ALG_RESULT_DATA block to the
application, primarily so the status and error flags can be seen. With
those available the application has the ability to detect that a stale
result has been provided so sensor_fetch_sample() can return -EAGAIN in
this case instead of -EIO, and it doesn't need to block which is
annoying.
This should also make the sensor usable on older Nordic Thingy:52
devices with outdated CCS811 application firmware that doesn't properly
implement the DATA_READY bit.

Proper use of the CCS811 requires maintenance of the BASELINE

Add the standard suite of trigger configuration options. Add driver

The original implementation relied on the DATA_READY bit of the STATUS
register to indicate when a reading was available. This bit remains
clear for the first several readings produced by the CCS811.
When INT_DATARDY is set in MEAS_MODE the nINT signal will remain
asserted until ALG_RESULT_DATA is read. If this is treated as a LEVEL
signal, which is the common case in Zephyr, gating the read of
ALG_RESULT_DATA on DATA_READY means the signal will never be cleared,
and the interrupt callback will be repeated immediately.
Since the STATUS register value is part of the ALG_RESULT_DATA block
just read the whole thing, and provide its content to the user only if
the DATA_READY bit is set.

The CCS811 has a measurement lifecycle that includes certain timing
constraints, including that calibration constants should not be applied
until the conditioning period has completed. If a device resets but the
CCS811 remains the process of inspecting current state and initializing
the device properly can be complicated.
Simplify this by forcing a reset of the device when the driver is
initialized. Should this cause hardship the necessary logic and
infrastructure to record time-of-last-reset across reboots and verify
measurement mode/baseline consistency can be added at that point.

The CCS811 can be in either boot mode (after powerup) or application
mode, and these modes have distinct register maps that share only some

case.

Correct handling of device encoded temperature values, which combine a
12-bit 2s complement signed value with a separate sign bit. Rework
conversion between device and sensor temperature representations to
support negative temperatures in both domains.
Use a much simpler trigger configuration where the alert is driven by
comparator output, rather than as an interrupt that requires a pair of
I2C transactions to read and clear the flag.
Refactor the trigger infrastructure to use the setup/handle/process
idiom, which reduces duplicated code and to correctly detect alerts
present when the triggers are set.
Completely replace the sample with something that demonstrates
updating upper and lower threshold values to track moving
temperatures.

- Added support for TMP117 in existing driver for TMP116
The Texas Instruments TMP117 is a higher precision upgrade
from TMP116. It shares most functionality, but has a
differing device ID.
This patch will run with the hardware IDs of both devices.
- Fixed an int promote issue in tmp116_channel_get
Negative temperature values in drv_data->sample were not
processed correctly.
The error occured during integer promotion from u16_t to s32_t
in this code line:
tmp = (s32_t)drv_data->sample * TMP116_RESOLUTION;
By first promoting to s16_t, the correct result is obtained:
tmp = (s16_t)drv_data->sample * (s32_t)TMP116_RESOLUTION;
- Made temperature resolution compatible to sensor API
The fractional part of the temperature was returned as a
multiple of 10^-7 deg.Celsius.
This differs from the resolution sugegsted by the sensor API,
which is 10^-6.
The driver is now returning temperature readings with
a resolution of 10^-6 deg. Celsius.
- The changed driver was tested using following hardware:

Low frequency and high frequency clocks had separate devices
while they are actually handled by single peripheral with single
interrupt. The split was done probably because opaque subsys
argument in the API was used for other purposes and there was
no way to pass the information which clock should be controlled.
Implementation changes some time ago and subsys parameter was
no longer used. It now can be used to indicate which clock should
be controlled.
Change become necessary when nrf5340 is taken into account where
there are more clocks and current approach would lead to create
multiple devices - mess.
