Align with other PWM drivers and treat the `pwm` parameter (described
ambiguously as "PWM pin") of the `pwm_pin_set_cycles` function as a PWM
channel, not an SoC pin. This will also make the driver consistent with
the `pwm-cells` property definition in the "nordic,nrf-sw-pwm" binding
and with related `DT_PWMS_*` macros.
The change described above requires also providing a way to specify
SoC pins that are to be assigned to the PWM channels. Hence, the commit
introduces in the "nordic,nrf-sw-pwm" binding the `channel-gpios`
property that replaces the `channel-count` one.

Add boolean properties to the binding for the nRF RADIO peripheral
to indicate whether the following features are supported:
- IEEE 802.15.4 mode
- 2 Mbps BLE mode
- coded BLE PHY
- high TX power settings
Set these properties appropriately in devicetree radio nodes for all
nRF SoCs.
Add also such properties and set them in appropriate nodes for nRF
flash controllers to indicate whether they support partial erase.

As Nordic SPI, I2C and UART buses can act as both slave and master,
these nodes can have different compatible properties, and are annotated
with a comment, instead of a compatible property. This forces boards to
put compatible properties in their definitions, which is unnecessary
boilerplate for most boards, as most boards acts as masters on these
buses.
Set master mode by default for these buses, to reduce boilerplate and
potential errors in board definitions. Boards that need to act as slave
nodes will just continue to override the compatible properties.
Likewise, existing boards that override this compatible property with a
master binding will not be affected by this change.

This file originally added a "nordic,nrf-sw-pwm" node with a few basic
properties that were common to all nRF51 and nRF52 series SoCs. There
is no implementation of SW_PWM available for other nRF series. At the
time this file has been created, there was only nRF91 apart from nRF5x,
but when nRF53 appeared, the name of this file became misleading.
Recent addition of common disabling of the systick node made it clear
that such common file for all nRF SoCs is convenient.
To prevent further confusion, rename this file to nrf_common.dtsi and
keep there only stuff actually common to all nRF series, moving the
SW_PWM related node to particular SoCs that use it (this is actually
consistent with how all other nodes, that also have some properties
common to several or even all nRF SoCs, are defined).

This commit introduces separate "compatible" strings for DTS nodes
representing different types of Nordic SPI peripherals. Previously
"nordic,nrf-spi" was used for both SPI and SPIM. SPIS was already
handled separately.
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/spi/
new binding for "nordic,nrf-spim" is added and common fields for all
3 types of Nordic SPI peripherals are extracted to a shared file
* dts/arm/nordic/
"compatible" properties in spiX nodes are updated (when there is no
choice as only one type of SPI 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/spi/
spi_nrfx_spim driver is updated with the new form of macros generated
from dts
* boards/

updated with the proper "compatible" property, according to the type
of SPI peripheral that is currently selected for the board by the
corresponding Kconfig choice option (SPI_x_NRF_SPI*)
