Falco/Slippy: Patch to remove redundant graphics initializations
gma_fui_init repeats the initializations already performed in gma_setup_panel.
These redundant initializations reset any gtt settings done before this call.
Hence, they had to be done again after call to gma_fui_init. However, the call
gma_fui_init is not required at all. Does not affect the behavior of suspend/resume.

Falco/Slippy: Patch to fix garbage on screen during graphics initialization in normal mode
Depending on the init_fb parameter:
1) For normal mode, first page is filled with zeroes and setgtt is used make all GTT entries point to this
same page
2) For developer/recovery mode, we init the gtt to consecutive pages
