The Powkiddy RGB30 device is similar to the Anbernic RGxx3 series,
however there are several differences which require deleting nodes in
order to properly define the hardware. This was deemed unacceptable
for the RK2023, so instead create a common include file for the
Powkiddy RGB30 and the Powkiddy RK2023. The only notable difference
between these Powkiddy devices are the panel in use, the device
name, and the PLL_VPLL frequency necessary to support the different
panels.

Since the RK2023 was released on the market first, name the common
include file after it.
