video: fbdev: mmp: fix sparse warnings about using incorrect types
Use ->screen_buffer instead of ->screen_base in mmpfb driver.
[ Please see commit 17a7b0b4d974 ("fb.h: Provide alternate screen_base
pointer") for details. ]
Also fix all other sparse warnings about using incorrect types in
mmp display subsystem.
