Add Anbernic RG353V and RG353VS

From: Chris Morgan <[email protected]>

Add support for the Anbernic RG353V and RG353VS handheld gaming consoles. These devices are extremely similar to the existing Anbernic RG353P.

Add support for the battery of the existing RG353P and RG503 too as part of this change, as to keep things compact we must first split the 353p devicetree into attributes common to all 353 devices and attributes that only exist for the 353P, 353V, and 353VS devices (which includes a different battery in the V and VS).

Lastly, add poll-interval to the parent tree so that it affects all existing Anbernic RGxx3 devices.

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.
