- use CONFIG_HAS_HW_NRF_* symbols consistently in nRF multi-instance
  drivers when creating particular driver instances
- remove unnecessary hidden Kconfig options that indicated the type of
  peripheral to be used by a given instance (e.g. SPI, SPIM, or SPIS)
  and enabled proper nrfx driver instance; instead, use one option per
  peripheral type and include the corresponding shim driver flavor into
  compilation basing on that option (not the one that enables the nrfx
  driver as it was incorrectly done so far in some cases)

Andrzej Głąbek 7058f3722e drivers: uart_nrfx_uarte: Revert workaround for bytes dropping
This effectively reverts the following three commits:
- 0f9f18843f
- 6812441099
- 326f7bd450
and also the changes that got copied to the nrf5340_audio_dk_nrf5340
board.

The workaround brings more harm than good. It already required many
tweaks in various tests to make them pass (because it introduced
a significant overhead in processing of the console UART interrupt)
and now it makes the I2S driver tests to fail. It's not reasonable
to add more tweaks in Zephyr tests just to keep this workaround in
the tree. Instead the root cause should be fixed (if the original
problem still occurs).

Krzysztof Chruscinski db6bfde8b3 drivers: serial: nrfx_uarte: Refactoring poll_out
Refactoring poll_out to be ready for handling preemption. uart_tx and
uart_fifo_fill modified so they are resilient to being preempted by
uart_poll_out.

Refactored uart_poll_out implementation to be common for interrupt
driven API and asynchronous API. In both APIs active state is detected
by evaluating state of ENDTX and TXSTOPPED events. If anyone is set it
means that new transfer can be started.

Patch is fixing existing issues:
- potential bytes dropping with flow control enabled
- busywaiting for ENDTX (asynchronous API) - poor performance
- potential bytes dropping during preemption
- potential uart_tx returning -EBUSY when interrupted poll_out

Andrzej Głąbek 011e9bac0b drivers: nrf: Remove no longer suitable dependencies on Kconfig options
Make I2C and SPI drivers for nRF SoCs no longer dependent on Kconfig
options that enable instances (i.e. I2C_x and SPI_x). Now these drivers
enable hardware instances when corresponding nodes in devicetree are
enabled (have status "okay").
For I2C, SPI, and UART drivers, instead of using Kconfig dependencies
to prevent enabling of hardware instances that cannot be used together
(e.g. SPIM1 and TWIM1), a file that signals invalid configurations with
build assertions is added to compilation.
Also dependencies on HAS_HW_NRF_* options are removed from Kconfigs
of I2C, SPI, and UART drivers, as for hidden options that activate
proper type of driver such dependencies are not actually helpful.

Andrzej Głąbek 97b07b943a drivers/serial/Kconfig.nrfx: Choose driver type basing on DT compatible
Remove prompts from Kconfig options `UART_x_NRF_UART*` that select
the type of nrfx driver (for UART or UARTE peripheral) to be used
for a given instance. This prevents the options from being modified
from configuration files.
Instead, make one of these options selected by default according to the
"compatible" property set for the corresponding UART node in devicetree.

This eliminates the need of changing both the "compatible" property in
devicetree and the Kconfig option selecting the driver type when a user
wants to switch between UART and UARTE for a given instance.

Since all `UART_x_NRF_UART*` options are made "hidden" by this commit,
all their occurrences in configuration files are removed.

Jun Li 32d23cb3aa driver: api: uart: remove exclusive config for async api
The PR removes the exclusive limit on enabling both UART_ASYNC_API
and UART_INTERRUPT_DRIVEN so that both options can be enabled
together for same uart driver.

Also, the interrupt handler will be used for both cases. So, enable
definition of interrupt handler for both.

However, nRF UART driver still wants to enable only one of them.
So, a new config is added to disable the code for UART_ASYNC_API
when the option UART_INTERRUPT_DRIVEN is enabled.

Make the following nRF peripheral drivers:
- ADC
- GPIO
- I2C
- SPI
- UART
- USB_DEVICE

Kconfig options enabling these drivers depend on both a given hardware
feature (e.g. I2C) and an nRF family SoC selected, so effectively they
will be automatically enabled only when it is adequate (and in most
cases these drivers are the only option for a given hardware feature
on nRF SoCs).
