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.

This commit removes API functions and macros which were deprecated in
2.2 release. GPIO drivers are updated accordingly.
Signed-off-by: Piotr Mienkowski <piotr.mienkowski@gmail.com>
Usually, we want to operate only on "available" device
nodes ("available" means "status is okay and a matching binding is
found"), but that's not true in all cases.
Sometimes we want to operate on special nodes without matching
bindings, such as those describing memory.
To handle the distinction, change various additional devicetree APIs
making it clear that they operate only on available device nodes,
adjusting gen_defines and devicetree.h implementation details
accordingly:
- emit macros for all existing nodes in gen_defines.py, regardless
of status or matching binding
- rename DT_NUM_INST to DT_NUM_INST_STATUS_OKAY
- rename DT_NODE_HAS_COMPAT to DT_NODE_HAS_COMPAT_STATUS_OKAY
- rename DT_INST_FOREACH to DT_INST_FOREACH_STATUS_OKAY
- rename DT_ANY_INST_ON_BUS to DT_ANY_INST_ON_BUS_STATUS_OKAY
- rewrite DT_HAS_NODE_STATUS_OKAY in terms of a new DT_NODE_HAS_STATUS
- resurrect DT_HAS_NODE in the form of DT_NODE_EXISTS
- remove DT_COMPAT_ON_BUS as a public API
- use the new default_prop_types edtlib parameter

These have been replaced by the appropriate call to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.

Updates the rv32m1 gpio driver and all associated boards to use new
device tree compatible gpio configuration flags. Implements new port
get/set/clear/toggle and pin_interrupt_configure functions recently
added to the gpio api.
Assumes the gpio api layer handles translating logical flags to physical
flags.
Stops quietly reconfiguring pinmuxes to gpio mode. The pinmux must now
be configured explicitly in the board's pinmux.c or in the application.
Tested with:
- samples/basic/blinky
- samples/basic/button
- tests/drivers/gpio/gpio_api_1pin
On boards:
- rv32m1_vega_ri5cy
