Peter Bigot bc34501892 drivers: use macro to define device structures
Replace individual device instance definitions with the macro that
expands to the equivalent change.

    F='struct device DEVICE_NAME_GET'
    git grep -l "$F" \
     | xargs sed -i -r \
       -e "s@$F"'\(([^)]*)\);@DEVICE_DECLARE(\1);@'

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

Kumar Gala 0a7d4e2135 devicetree: Change DT_FOREACH_IMPL_ to not insert semicolon
Remove semicolon between instance invocations of DT_FOREACH_IMPL_ and
thus DT_INST_FOREACH.  This provides more flexibility to the user.  This
requires we fixup in tree users to add semicolon where needed.

Kumar Gala 5f94e593c0 drivers: i2c: i2c_sam_twi: rework device tree support
Reworked i2c_sam_twi driver to utilize new DT_INST macros as part of
this rework we also now get pin ctrl/mux configuration information
from the device tree instead of via Kconfig and defines in soc_pinmap.h

We remove defines from dts_fixup.h and soc_pinmap.h and associated
Kconfig symbols that are no longer needed due to getting all that
information from devicetree.

Andrzej Głąbek 20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
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
