arm64: dts: rockchip: add Anbernic RG353V and RG353VS

Anbernic RG353V and RG353VS are both RK3566 based handheld gaming devices
from Anbernic.

They are functionally very similar to the RG353P with the following
distinct differences:
 - The battery size of the RG353V and RG353VS is 3200mAh instead of
   3500mAh.
 - The audio uses the PMIC's internal amplifier for a mono speaker
   instead of an external amplifier with stereo speakers.
 - The GPIOs for the R1 and R2 buttons are switched.

As for the differences between the RG353V and RG353VS, they are as
follows:
 - The RG353VS has no touchscreen on i2c2.
 - The RG353VS has no eMMC.
 - The RG353VS has 1GB of RAM instead of 2GB.
