Lowest power consumption can be achieved when uarte peripheral
is disabled when not used. In low power mode, need for both
directions is tracked and if both are no in use peripheral is
disabled. TX disabling is instant but RX requires flushing RX
fifo because data in hardware fifo is lost when peripheral is
re-enabled.

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

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.

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.

Use this short header style in all Kconfig files:
# <description>
# <copyright>
# <license>
...
Also change all <description>s from
# Kconfig[.extension] - Foo-related options
to just
# Foo-related options
It's clear enough that it's about Kconfig.
The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

In some applications where power management is used, it is not expected
that the GPIO pins of the UARTE is reconfigured upon power state change.
Added a Kconfig option to disable the UARTE driver management of GPIOs.
It defaults to y in order to not affect current behavior unless the user
configures it specifically.

Not all serial drivers support ASYNC operation and if they do,
they might not support it on every SoC.
Add the SERIAL_SUPPORT_ASYNC option to indicate ASYNC operation

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.

In Nordic SoCs, SPI and TWI peripherals with the same instance number
share certain resources and therefore cannot be used at the same time
(in nRF91 Series this limitation concerns UART peripherals as well).
This patch adds Kconfig checks ensuring that only one of such mutually
exclusive peripherals can be enabled.

Make the following nRF peripheral drivers:
- ADC
- GPIO
- I2C
- SPI
- UART
- USB_DEVICE
enabled by default so that users do not need to explicitly enable them
in their applications after choosing an nRF SoC as the build target.
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).
