Add a config structure for each port and use the devicetree GPIO pin
count to initialize it. Simplify device initialization by using
instance number as only variation point.

Almost all drivers support 32 pins, though some support less.
Eventually this should be specified in every SOC binding, but until
then provide a default so GPIO drivers can be updated to use this.

This breaks down the GPIO controller definition in DTS into
multiple entries. This allows these controllers to be
referenced by other DTS, and test board overlay files.
And also we can remove the entries in the dts fixup file.

Converts the usdhc driver to the new gpio api. Updates the
device tree for the mimxrt1050_evk board to set appropriate active
high/low polarity for the power and card detect pins.
Note that the driver doesn't actually support interrupts yet. It
initializes a gpio callback for the card detect pin, but never actually
enables the gpio interrupt. This incomplete behavior is left as-is,
since the purpose of this patch is only to convert the driver to the new
gpio api, not to add new features.

were added to the dts file.

IO extenders may provide input signals to LEDs or sensors where
leaving the signal undriven may result in increased power consumption
or misbehavior. The SX1509B powers up with all signals configured as
inputs. Provide a way to indicate which pins should be set as output,
and their initial signal level, when the device is configured.

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.

Convert the GPIO based driver to the new GPIO API. (Only the
gpio_configure() call is affected).
Move configuration to DT where appropriate for both SPI and GPIO
drivers, only leaving the SPI vs. GPIO decision in Kconfig (in
addition to the basic enable for the driver.) Move some files around
to clean up as a result of this change.
led_ws2812 sample changes:
- make the pattern easier to look at by emitting less light
- use led_strip alias from DT to get strip device, allocate
appropriate struct led_rgb buffer, etc.
- move the pins around and remove 96b_carbon support (I have no board
to test with)
GPIO driver specific changes:
- str is required to write OUTSET/OUTCLR, not strb. The registers
are word-sized.
- the str[b] registers must all be in r0-r7, so "l" is the correct GCC
inline assembly constraint for both "base" and "pin"
SPI driver specific changes:
- match the GPIO driver in not supporting the update_channels API
method, which never made sense for this type of strip
- return -ENOMEM when the user tries to send more pixel data
than we have buffer space for instead of -EINVAL

ARM cores may have a per-core architected timer, which provides per-cpu
timers, attached to a GIC to deliver its per-processor interrupts via
PPIs. This is the most common case supported by QEMU in the virt
platform.
This patch introduces support for this timer abstracting the way the
timer registers are actually accessed. This is needed because different
architectures (for example ARMv7-R vs ARMv8-A) use different registers
and even the same architecture (ARMv8-A) can actually use different
timers (ELx physical timers vs ELx virtual timers).
So we introduce the common driver here but the actual SoC / architecture
/ board must provide the three helpers (arm_arch_timer_set_compare(),
arm_arch_timer_toggle(), arm_arch_timer_count()) using an header file
imported through the arch/cpu.h header file.
