Make sure M68K sync and target cycles are updated after loading a savestate. Fixes an issue in which loading a savestate would result in things being unresponsive until emulation cycle caught up to whatever the pre-state load sync cycle was

Go back to resetting the refresh counter after a DMA. Probably not quite correct as it is probably reset on VDP triggered refresh, but this is close enough for now given the general limitations with my refresh code.
