Prevent "unique_unit_address_if_enabled" warnings from being reported
for nRF52 Series SoCs, where certain nodes need to be enabled with
the same base addresses. These can be (depending on a given SoC):
- power@40000000 & clock@40000000
- power@40000000 & clock@40000000 & bprot@40000000
- acl@4001e000 & flash-controller@4001e000

A follow-up to #44181, this time fixing the pyocd target parameters to
match the actual hardware on the board.

The jlink executable expects a fully qualified IC name, and not just the
family. Apply to all Nordic boards.

Add a new DT property named "pixel-group-size" that allows users to
configure the driver to refresh the matrix by illuminating multiple
LEDs in particular rows simultaneously. This way the maximum possible
brightness of the LEDs can be increased (as they can be lit longer)
and the timer interrupt handler is executed less frequently, what
results in decreased CPU load, but more GPIOTE/PPI channels needs to
be allocated if the PWM peripheral cannot be used. Thus, it is left
to users to select the configuration that suits them best.
Update definitions of both the bbc_microbit boards with this new
property, using the maximum available group size (to achieve maximum
possible brightness). For v2, no new resources are used (only all
channels in the already used PWM peripheral are now utilized).
For v1, two more GPIOTE and PPI channels are allocated.

Both BBC micro:bit v1 and v2 boards are equipped with a LED matrix
driven by the SoC GPIOs. Add "nordic,nrf-led-matrix" compatible nodes
to DTS files of both these boards so that the nRF LED matrix display
driver can be used for them.

USB devicetree nodes in Zephyr have different names,
mostly derived from the designations in data sheets.
Add zephyr_udc0 (USB device controller) nodelabel to
specific USB node to allow generic USB sample to be build.

These changes turn out to have been incompatible with the way pinctrl
drivers are going to work, so we need to go back to what we had before
until we can agree on a better approach.
Squash of the following reverts:
Revert "boards: nrf: fix deprecated I2C properties"
This reverts commit 2a4ac9ac02.
Revert "samples: switch nrf overlays to sda-gpios, scl-gpios"
This reverts commit 01bb08e7d8.
Revert "boards: nrf: switch to sda-gpios, scl-gpios"

Move the BOARD.dts files for Nordic-based boards to use the new I2C
devicetree properties for specifying the SDA and SCL pins.
This was done with a script.

The board's main I2C bus controller doesn't have a compatible set, so
it's not detected as an I2C bus at all.
This breaks the build when trying to build the samples/sensor/lis2dh
application with the lis2dh sensor on that bus.

The BBC micro:bit v2 is a mini-computer that has been
designed to make the coding fun and easy to learn.
The micro:bit v2 is completely programmable so you can
easily bring your ideas to life! From making games to
creating music and even controlling robots.
The micro:bit comes with neat hardware such as a 25 LED
display, buttons, in-built speakers, Bluetooth 5 & Mesh
connectivity and sensors for temperature, motion & light.
