There appears to be severe timing issues in the ppu which result in
regressions with these gates enabled. They are commented out for now,
but will be re-enabled once the timing issues in the PPU are fixed

note: while the logic is there, the instruction currently does not do
anything because we don't halde it in Cpu::step(). The code that does is
currently commented out and there should be some underlying bugs still
present. Nevertheless it is a good start
