This commit removes API functions and macros which were deprecated in
2.2 release. GPIO drivers are updated accordingly.

The mcux lpc driver assumes that PINT interrupts are assigned to GPIO
port instances in groups of four, meaning that GPIO0 uses PIN_INT0-3 and
GPIO1 uses PIN_INT4-7. There was a mistake in the pin assignment
calculation that caused GPIO1 to incorrectly attach pins to PIN_INT0-3.
This caused the gpio isr to be invoked with what appeared to be the
wrong device argument and therefore not invoke any of the expected gpio
callbacks. But actually, it was the wrong irq that fired.
Found when adding support for the accelerometer interrupt on the
lpcxpresso55s69 board.

Use gpio_pin_t uniformly when passing pin indexes to the driver. Use
gpio_flags_t uniformly when passing flags to the driver. Change name
of pin configuration function in API function table to be consistent
with other API functions.

The only remaining port operations have dedicated API function table
entries. Remove the defines for access op (mode), and remove support
for access op from all implementations.

The last external reference to these was removed when the pin
write/read functions were deprecated. Remove the syscall support, API
function table entries, and implementation from all drivers.

These have been replaced by the appropriate call to
gpio_pin_interrupt_configure(). While the disable function could be
implemented using the new functionality, the enable function cannot
because the interrupt mode is not available. Consequently we cannot
replace these with equivalent functionality using the legacy API.
Clean up the internal implementation by removing the inaccessible
port-based enable/disable feature, leaving the pin-based capability in
place.

Add the common config structure as a prefix of the driver-specific
config structure and use the devicetree GPIO pin counts to initialize
it.

LPC GPIO architecture uses multiple devices.
GPIO input is routed via INPUTMUX to the PINT
device which roots the interrupt to NVIC.

Updates the mcux lpc driver and all associated boards to use new
device tree compatible gpio configuration flags. Implements new port
get/set/clear/toggle functions recently added to the gpio api.
ISR functions to be added later.

move gpio.h to drivers/gpio.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

Validates the gpio pin number before using it to index into a
memory-mapped register array. Otherwise, a user could send a high pin
number and cause an out-of-bounds access.

We have been combining imported mcux drivers into a flattened directory
structure to maximize driver reuse, but the introduction of additional
nxp soc families (lpc and imx) to zephyr has introduced driver naming
conflicts. This caused us to rename and modify imported files, such as
fsl_gpio.c/h, to make them unique across all three nxp soc families.
This makes updating the the mcux drivers complicated, especially for the
lpc family.
Reoganize the mcux drivers into soc family subfolders, so we can just
copy all the drivers from an mcux distribution (which is done on an
soc-basis) into the appropriate soc family folder. Undo all of the
naming changes that occurred when lpc and imx drivers were originally
imported. Undo the accidental squashing of the kinetis watchdog and dcdc
drivers that occurred when the imx drivers were introduced.
The drawback to this approach is that we have duplicate files when the
same hw ip modules exist in multiple soc families, however there are
only few cases where this occurs, such as fsl_lpuart and fsl_trng.

Add gpio mcux driver which can be used for lpcxpresso54114 and other lpc
socs. In this driver, CMSIS register access is made for GPIO.
Option for access by GPIO Pin is provided as of now.
