playch10.cpp: A few more cleanups. (#9352)
- Nametable RAM is now 2K, except for the two games (Rad Racer II, Gauntlet) that have extra RAM on daughter boards. - Removed unnecessary overridden machine/video start code for PinBot. - Added an address map for the PPU. - Further simplified initialization code for games that have VRAM or special RP5H01 usage. - Lots of conversion to C++-style comments with a few corrections along the way.
