Martí Bolívar 7e0eed9235 devicetree: allow access to all nodes
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

Tomasz Bursztyka 97326c0445 device: Fix structure attributes access
Since struct devconfig was merged earlier into struct device, let's fix
accessing config_info, name, ... attributes everywhere via:

grep -rlZ 'dev->config->' | xargs -0 sed -i 's/dev->config->/dev->/g'

Peter Bigot 7c95d503b0 gpio: clean up internal API function prototypes
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.

Peter Bigot 1947481cce gpio: deprecate gpio pin callback enable and disable API
These have been replaced by the appropriate call to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.

Maureen Helm 03c3b4bed5 gpio: Update rv32m1 gpio driver to use new gpio api
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
