staging: sm750fb: Fix bugs introduced by early commits

Browse source 
Early commit 30ca5cb63c ("staging: sm750fb: change definition of
PANEL_PLANE_TL fields") and 27b047bbe1 ("staging: sm750fb: change
definition of PANEL_PLANE_BR fields") modify the register bit fields
definitions. But the modifications are wrong, because the bit mask of
"bit field 10:0" is not 0xeff, but 0x7ff. The wrong definition bugs
makes display very strange.
