Update all drivers that have vectorial data to return all 3 channels (X,
Y and Z) if the chan parameter is _ANY.
Also fix a compile bug in LSM9DS0 MFD driver.

This accidentally snuck by between iterations of the workqueue patches.
In v1 there was a sensor-specific workqueue, which we then turned into a
global one.

Remove the homegrown sensor delayed work API in favor of using the
system-wide workqueue. Drivers still have the option of using their own
fiber.
In a second step, drivers can be refactored to start and use their own
workqueue.

Rename sensor_value_type enums from SENSOR_TYPE_* to more concludent
name SENSOR_VALUE_TYPE_*. This change is required if we want to
introduce SENSOR_TYPE_* (SENSOR_TYPE_ACCEL - if the sensor/driver
supports accelerometer, SENSOR_TYPE_MAGN - etc.) in the future.
Also it is more clear with this notation what these enums are referring
to.

Now you can specify the sensor type you want to fetch using
sensor_sample_fetch_chan. This will inform the driver that you want only
one type of data updated, leaving the others unchanged and enabling
different sampling rates for multi function devices (MFDs).

Since sensors' API uses SI units, all attributes and channel reading use
SI units. Hence, conversions from other units to SI are necessary.
This patch adds helper for converting:
* m/s^2 to Gs (and vice versa);
* degrees to radians (and vice versa);

* SENSOR_ATTR_OFFSET: for setting offsets in order to adjust the read
values;
* SENSOR_ATTR_CALIB_TARGET: for setting target that the chip internal
algorithms need to converge to when calibrating;

Add enum value for full-scale attribute, so we can implement runtime
alteration if needed.

This patch replaces all occurences of the macro DEV_INVALID_OP by
-ENOTSUP at the driver level. So this patch touch the files under
drivers/, include/ and samples/drivers/ when applicable.
This patch is part of the effort to transition from DEV_* codes to
errno.h codes.

Sensor drivers expose one or more channels, corresponding to each
individual quantity they can measure. Such quantities may be different
altogether (e.g. temperature and pressure) or different axes for the
same unit (e.g. three axes of acceleration). Before reading channels, a
driver must be explicitly instructed to obtain a sample from the device.
This helps accommodate sensors which can only read all channels at once,
and also helps ensure coherence of measurements and optimize I2C/SPI
traffic.
Channels can be read as floating point values or struct sensor_value.
The latter consists of a pair of integers and a type field which
dictates how to interpret said integers. The most common type is INT
(where the second value is ignored) or INT_PLUS_MICRO, which means the
second value should be multiplied by 1.0e-6 and added to the first.
A sensor driver may support one or more triggers, corresponding to
interrupts or timers. Registering for a trigger involves supplying the
driver with a callback which is called when a condition is reached.
Examples of trigger types are: data ready, timer expiration, any-motion,
near/far.
Finally, sensors support attributes such as sample frequency,
measurement accuracy or threshold values for triggers. However, runtime
configuration is discouraged, in the interest of keeping code simple.
