Put all the devicetree configuration data into a config structure in
flash, which removes some ultra-long identifiers from the code and
makes it more readable, and prepares for multiple instance support.
Consistently use the interrupt signal datasheet name for all objects
that are specific to that signal, including configuration structure
tags and function names.
Update the trigger idiom for setup/handle/process stages.

Update the gpio_counter sample app for the UP Squared board:
() Update configuration calls to use new flags.
() Separate pin configuration into setting it to input, and
setting the pin for interrupt.
() Use gpio_pin_set() instead of gpio_pin_write().

This adds a board overlay for up_squared to be used with
the GPIO sample. Using the overlay is because the pins
being used are not actually LED and switch but GPIO pins
used as such.

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.

Update bluetooth hcp spi driver to new GPIO API.
Following changes have been done:
- Use new gpio api functions
- Get reset, irq and cs flags from dt defines
- Define reset pin as active low and invert set/unset logic.
Tested on disco_l475_iot1 and 96b_carbon.

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.

The public API for GPIO flags should use unsigned values, and for
MISRA compliance the size should not be platform-dependent. Add a
typedef for generic flags.
Also add typedefs for pin indexes and devicetree flags so these can
be safely recorded from devicetree property values without risking
loss of information if more flags are added in the future.

For this board all 16 pins on the SX1509B should be configured as
outputs. Six of them are active-low LEDs. Provide configuration so
those six are initialized to output high, and the remainder to output
low.
Two of the pins control the behavior of the CCS811 gas sensor. By
driving them low on boot the baseline current draw of the board is
reduced by 100 uA.

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.

The cached state of the output must be managed under mutex, but the
original toggle implementation read the current state outside the
mutex and used it to update the state. Rework the internal API so
that toggle is done within the mutex, distinct from masked set.

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

Extend the physical level GPIO_OUTPUT_{HIGH,LOW} configuration with
