Use new API to configure and interact with GPIOs. Move GPIO
initialization from sample into driver. The existing physical/line
level control has been kept rather than converting to logical level
signals.
Also improve error messages.

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().

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

Convert the sample to use the new GPIO API and additionally:
- add some error messages for unsuccessful GPIO API calls
- correct the index of `def_val` element used in the `right_button`
callback, to match the one used when the callback is installed
- use flags defined in devicetree for the pin that drives the LED
(for consistency, as this does not make much difference for a pin
that is only toggled)

warning: NET_SOCKETS_POSIX_NAMES

This test uses bare variables to synchronize state between threads,
but had forgotten volatile qualifiers on all the data. So the
compiler was free to reorder and make assumptions that aren't valid
when the values are being written from other CPUs.
Single-cpu operation was fine because the code would always hit an
external function call like k_sleep() that would force it to re-read
from memory every time there was a context switch (timeslicing isn't
enabled on this test and the threads are cooperative), but on SMP the
volatiles can change at any time and we could see spurious state
mixups and hangs.
