bus/nes: Continued work on VRC4 and clone boards. (#8713)
- Tweaked VRC4 class to make it easier to extend for clones and multicarts. The main new pieces are: a centralized and more flexible function for PRG banking and an overridable IRQ acknowledge function. - Added support for 830506C board. - Added support for unknown board for Yu Yu Hakusho/Dragon Ball Z 2-in-1. - Made a small simplification to TF1201 using new IRQ function. New working software list additions (nes.xml) ----------------------------------- 1994 Super HiK 4 in 1 (JY-005) [famiac, NewRisingSun] Software list items promoted to working (nes.xml) --------------------------------------- 2 in 1 - Yu Yu + Dragonball Z
