Sunplus Plug & Play work (cleanup + fixes + notes based on wrlshunt code analysis) (#6010)
* misc sunplus work (nw) * unbreak a few things, remove some test code (nw) * mask shift values, maybe correct based on code study (nw) * refactor (nw) * notes based on code study (nw) * force a different codepath in wrlshunt, static screen, but differnet, no crash, need to see if it's valid (nw) * test (nw)
