Revert "ARM: 7493/1: use generic unaligned.h"

This reverts commit ca3d26d96b5bf1dfaade35321c938f427ad98805.

The commit was causing unexpected reboots / hangs probably because of
use of Linaro GCC 4.9 or the other optimizations previously applied
to this custom kernel.
Update lcdc_samsung_ancora.h
