oneplus-one: fix swapped red and blue (!287)

The problem behind swapped red and blue is inverted byte order in
framebuffer driver pixel format.
This patch sets the correct byte order in the framebuffer driver.

The previous workaround patch is removed because it fixes improperly
the red-screen issue, causing the swapped red and blue problem
that this commit solves
