- properly performs gpu/backlight reset
- nukes vram so the initrd had to be moved to arm9 memory, and have its size (at least temporarily) limited to 256k
- moved brightness control to the ARM11
- moved HID updating to the ARM11
- moved screen init from ARM9 to the ARM11, always performed unconditionally
- removed unnecessary SCREENINIT and SET_BRIGHTNESS pxi commands
and other stuff I probably forgot about
- moved common.h from the ARM9 tree to the common code tree
- does proper deinit now on the ARM11 side
the bug that caused it to fail to launch some FIRMs has been fixed - it can even boot stock FIRMs
