From: Chris Morgan <macromorgan@xxxxxxxxxxx>
Add support for the Anbernic RG353PS. This device is identical in form
factor to the RG353P and has the following hardware differences:
- No touchscreen is present on i2c2 (or at all).
- Only contains 1GB of RAM.
- Has no eMMC.
- Only appears to ship with the 2nd revision of the display panel.
Note that the display panel has been added to the st7703 panel driver
in a separate commit series.
