video: fbdev: mmp: fix sparse warnings about using incorrect types 

Use ->screen_buffer instead of ->screen_base in mmpfb driver.

[ Please see commit 17a7b0b4d9 ("fb.h: Provide alternate screen_base
  pointer") for details. ]

Also fix all other sparse warnings about using incorrect types in
mmp display subsystem.
