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.

Martí Bolívar 87e1743ae0 devicetree: replace DT_HAS_DRV_INST with DT_INST_FOREACH
Make drivers multi-instance wherever possible using DT_INST_FOREACH.
This allows removing DT_HAS_DRV_INST in favor of making drivers just
do the right thing regardless of how many instances there are.

There are a few exceptions:

- SoC drivers which use CMake input files (like i2c_dw.c) or otherwise
  would require more time to convert than I have at the moment. For the
  sake of expediency, just inline the DT_HAS_DRV_INST expansion for
  now in these cases.

- SoC drivers which are explicitly single-instance (like the nRF SAADC
  driver). Again for the sake of expediency, drop a BUILD_ASSERT in
  those cases to make sure the assumption that all supported SoCs have
  at most one available instance is valid, failing fast otherwise.

Martí Bolívar bbde37113f adc: nordic: move to new DT API and kconfig style
Use the new devicetree API. Remove per-board enabling of ADC_0 by
setting ADC_0 to default y when the 'adc' node label points at an
enabled node of the expected compatible (depending on SoC).

Andrzej Głąbek b1d5eed262 drivers: nrfx: Update implementations after switching to nrfx 2.0.0
Update calls to nrfx HAL functions to reflect API changes introduced in
nrfx 2.0.0. All these functions are now called with the first parameter
pointing to the structure of registers of the relevant peripheral.
Also a few functions got renamed:
- nrf_gpiote_int_is_enabled to nrf_gpiote_int_enable_check
- nrf_gpiote_event_is_set to nrf_gpiote_event_check
- nrf_rng_event_get to nrf_rng_event_check
- nrf_rng_int_get to nrf_rng_int_enable_check
- nrf_rtc_event_pending to nrf_rtc_event_check
- nrf_rtc_int_is_enabled to nrf_rtc_int_enable_check
- nrf_timer_cc_read to nrf_timer_cc_get
- nrf_timer_cc_write to nrf_timer_cc_set

Default configuration values were removed from nrfx_config files,
so the drivers pwm_nrfx and spi_nrfx_spis no longer can use those.

Function nrfx_pwm_init() now takes one more parameter - context pointer
that is passed to the event handler, not used in the pwm_nrfx driver.

HALs for UART and UARTE now allow configuration of the parity type
and the number of stop bits, for SoCs that provide the corresponding
registers.

Andrzej Głąbek 0906a51dac drivers: adc: Fix handling of invalid sampling requests
Commit aad21ecb31 introduced an incorrect
pattern of handling ADC sampling requests with invalid parameters in
both nRF ADC drivers. After discarding such request, the drivers do not
release properly the access lock and therefore become unusable.
Unfortunately, this pattern were later on copied in all other ADC
drivers in the source tree.
This commit adds the proper lock releasing in all the affected drivers.

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

Andrzej Głąbek aad21ecb31 drivers: adc: Add shims for nrfx ADC and SAADC drivers
This commit adds translation layers to make nrfx drivers for the nRF
ADC (nRF51 series) and SAADC (nRF52 series) peripherals accessible via
the Zephyr's API. The SAADC peripheral is accessed using nrfx HAL only
as it turns out that usage of the nrfx driver in this case would be
inconvenient and would unnecessarily complicate the shim.
