Added return to boot menu to a800 mcc cores
Added Drive turbo selection. Fixed a few builds. Added which target is building to output. Run up to 3 jobs at once during build.
Split the concept of hsync, vsync and composite sync. When composite sync used tie vsync high. The offset hsync pulse of pal/hsync is only present for 15khz composite sync. Remove rom selection since its unused.
Share the USB PS2 override logic. Wire up USB to controllers on the MCC216
start of USB support - ram timing issue fixed
