Greyscale library: Optionally put the greyscale ISR on COP on portalplayertargets (only use with the grey_info structure in IRAM atm\!). This speeds up doom by ~50%, and makes mpegplayer work without stuttering audio on targets using it (measured on iPod 2nd Gen and Mini 2nd Gen). It needs corelocking certain functions in the LCD driver on 1st/2nd Gen.
