Bananapi R3 has a Power socket entended for using external SATA drives. This Socket is off by default but can be switched with gpio 8.

Add an overlay to activate it.

v4:
- rebased on 6.13-rc1 without the full-dtb patch
v3:
- make sata overlay better readable
v2:
- rebase on the patch "add dtbs with applied overlays for bpi-r3"
- add sata-overlay to the full dtbs
