The UC8176 and UC8179 chips that exist in tree have subtly different
register layouts. Use separate compatible strings for these chips and
a quirks structure that describe device-specific behavior.

The GD7965 driver is really just a vendor name for the UltraChip
UC8179. Rename the driver to UC81xx since there are other chips in the
family (e.g., the UC8176) with an almost identical register interface.

Some panels using this driver don't provide tcon/cdi/pwr/softstart
values in their reference code. It is normally expected that the right
values will be loaded from OTP in such cases. Make these values
optional to support such panels.

All in tree device drivers use some form of DEVICE_DT_GET
so we no longer need to require label properties.

Add 'inversion-on' property to st7735r.
Issue INVON(21h) command on initializing if inversion-on was enabled.
As a result of this command, the display color is inverted.
Otherwise, INVOFF(20h) will be issued.

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.

Add a display driver and the corresponding devicetree binding for a LED
matrix with rows and columns driven by nRF SoCs GPIOs. Such matrix can
be found, for example, in the BBC micro:bit boards.

Software reset is already implemented in the driver when the
`reset_gpio` is not defined. However it could not be activated
because the `reset_gpio` is a required field in the DTS
binding.

Add a new display-inversion property to ili9xxx based display drivers to
send a "Display Inversion ON (0x21)" command during initialization.
This seems to be required for some ILI9xxx based displays to work
correctly, such as BuyDisplay ER-TFT028A2-4 (ILI9341 basd IPS display).

Make driver generic for multiple ILI displays. The adopted strategy is
to share all driver code except register initialization, which has been
found to have some specific registers/values depending on the
controller.
The driver has been adjusted to support multiple compatibles.
