Memreserve calculations

Memory hole like kernel 3.1.10

/*
 * Carveouts for multimedia and ram console
 * 128MB - multimedia
 * 8MB - fb1
 * 16MB - fb2
 * 1MB - ram-console

Problems left

1. Slow data/system EXT4 format from recovery
2. UDC usb works only if inserted before poweron
3. Hardware video overlays freezes (Probably memory clock problem)
4. No power button/lid events from nvec
5. Battare uevents (Patch from 3.1 fits 3.18)
