Bump sunxi to 5.7.y (#2056)
* Bump sunxi to 5.7.y
* Further cleanup 32bit works, 64bit needs more patches adjustement
* Also arm64 boots, SPI flash areas were refactored, new location is a bit fuzzy, leaving behind
* More fixed and cleanings, both variants builds now, but without overlay support
* fix sunxi overlays in AR-329 branch
