cecea7b536 drivers: i2c_nrfx_{twi, twim}: Remove potential I2C deadlock
Remove K_FOREVER wait on completion_sync.
In some situations (a short on I2C SDA line for example), this
semaphore will never be released and therefore we should not wait
it forever.
Instead we wait for a maximum of 100msec and return an error if we
weren't able to retrieve the semaphore.
In such situation, the program is not stuck anymore, but the I2C
driver must be uninit then init again to work again.

Fixes #25076.

668d401293 modules: hal: nordic: Define NRFX_ASSERT as __ASSERT_NO_MSG
Update hal_nordic's revision, so that NRFX_ASSERT uses __ASSERT_NO_MSG
directly, not through the assert macro that comes from from libc,
as the definition of the latter might be different when some specific
libc version is used, and this could generate troubles.

Replace also uses of assert() with __ASSERT_NO_MSG() in nrfx driver
shims that use this macro without including the corresponding header
file (i.e. that implicitly rely on assert.h being included from
nrfx_glue.h, which is no longer the case).

dd4c57d564 dts: Use separate compatibles for Nordic TWI/TWIM/TWIS peripherals
This commit introduces separate "compatible" strings for dts nodes
representing different types of Nordic TWI peripherals. Previously
"nordic,nrf-i2c" was used for both TWI and TWIM, and TWIS was not
supported.

Quite a few files need to be touched by this commit but the changes can
be divided into groups of related or very similar ones, distinguishable
by the initial part of the path to the modified file:

* dts/bindings/i2c/
  new bindings for "nordic,nrf-twim" and "nordic,nrf-twis" are added
  and the one for "nordic,nrf-i2s" is renamed to "nordic,nrf-twi",
  common fields for all these bindings are extracted to a shared file

* dts/arm/nordic/
  "compatible" properties in i2cX nodes are updated (when there is no
  choice as only one type of TWI peripheral is available) or replaced
  with a comment pointing out that the proper type of peripheral needs
  to be picked at some upper layer

* drivers/i2c/
  both flavors of i2c_nrfx drivers are updated with the new names of
  macros generated from dts

* boards/
  all i2cX nodes in dts files for boards equipped with an nRF chip are
  updated with the proper "compatible" property, according to the type
  of TWI peripheral that is currently selected for the board by the
  corresponding Kconfig choice option (I2C_x_NRF_TWI*)

Make use of the new flag introduced in nrfx v1.7.2 that suspends
transfers, in order to properly handle scattered I2C transactions,
especially to perform i2c_burst_write() in the way expected by
display drivers, i.e. as a continuous transaction on the bus,
without the repeated START between its two parts.

To fix this, let's replace the use of static_assert() with a more
generic macro: BUILD_ASSERT_MSG()  This should work across minimal
libc, newlibc and c++.

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
