[PATCH v3 0/5] Add more RK3326 gaming handhelds

[Maya Matuszczyk]

This patch series adds Odroid Go Advance, Odroid Go Super(without
display) and Anbernic RG351M.

RG351P uses almost the same motherboard, and I'm not sure how to handle
it. RG351P DTS file would look exactly the same, aside name change.

Changes from V2:
- Fixed a typo
- Added "v3" tag, sorry!
- Added the cover letter in a way that shouldn't get swallowed by gmail
  this time

Changes from V1:
- Addressed Chris Morgan's comments
- Added RG351M
- Added RG351M and Odroid Go Super
