PRE_KERNEL_1 is to be used for devices that have no dependencies
and do not use kernel features, such as those that rely solely on
hardware present in the processor/SOC. This commit updates these
gpios to initialize during the PRE_KERNEL_1 rather than the
POST_KERNEL. Some SoC drivers are moved to PRE_KERNEL_2 due
to dependencies.
A lot of 'other' drivers can depend on GPIOs though phandles
(such as reset lines, data or command gpios, etc...). Most of these
drivers that would need this would come up on the POST_KERNEL,
and it's likely the driver may not be up yet as it should be defined.

Refactors all of the on-chip GPIO drivers to use a shared driver class
initialization priority configuration, CONFIG_GPIO_INIT_PRIORITY, to
allow configuring GPIO drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.
Most drivers previously used CONFIG_KERNEL_INIT_PRIORITY_DEFAULT or
CONFIG_KERNEL_INIT_PRIORITY_DEVICE, therefore the default for this new
option is the lower of the two, which means earlier initialization.
Driver-specific options for off-chip I2C- or SPI-based GPIO drivers are
left intact because they often need to be initialized at a different
priority than on-chip GPIO drivers.

The primary problem was that the callback was being invoked twice,
which broke the tests.
A secondary issue is that when two level tests occur consecutively the
second will fail. Instrumentation confirms that the registers are
being configured correctly, and ip indicates that the condition was
detected, but the interrupt does not occur. Tests pass as long as no
level test precedes the failing test.
It's not clear whether this is an issue with the PLIC, or the GPIO
implementation (hardware or software). As "normal" GPIO applications
appear to work we'll run with it and keep an issue open.

These have been replaced by the appropriate call to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.

It needs to verify if the callback was not already installed, and if so:
if is was in controller's list.
It should return an error in case the node is not found though it was

If already inserted, it will be silently removed but added again, to
avoid circular list as stated in the bug.

These changes were obtained by running a script created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:
1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
#define X Y)
3. Check if that name is also the name of a Kconfig option
3.a If it is, then do nothing
3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
(.c, .h, .ld)
Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.
Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c
