Memreserve calculations

Memory hole like kernel 3.1.10

/*

 * 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 and lid events from nvec
5. Battare uevents (Patch from 3.1 fits 3.18)
