sprdfb_check_var() has two problems:
I) it is not buffering-aware, which all Spreadtrum devices use;
II) it checks values that are already in yres_virtual, not those that we
are trying to overwrite.
Those problems stop X11 and charging-sdl from working properly.
X11 error:
(EE) FBDEV(0): FBIOPUT_VSCREENINFO: Invalid argument
This patch fixes first problem, however, the correct way is fixing
the second one, as this might have less side effects.

By default, color channels on Spreadtrum devices are swapped. This patch makes kernel use BGR565, which has normal color channels.
