MotoGP: Compat hack to disable framebuffer readbacks.

Browse Source 
This is the only known game to copy its framebufer to RAM before display on every frame and we already have a
hack so we can display the high resolution framebuffer, but we still did the readback for no good reason.

This eliminates the readback.
