Falco/Slippy: Patch to refactor haswell/gma.c and mainboard/google/slippy/i915io.c

Browse Source 
A large portion of documented registers have been initialized using macros. Only a few
undocumented registers are left out. i915io.c looks lot more cleaner by removing redundant
calls. However, some more work is required to correctly identify which calls are not required.

All the io_writes are replaced by gtt_writes.
