drm/mipi_dbi: Use simple right shift instead of double negation
GCC complains about dubious bitwise OR operand:
drivers/gpu/drm/drm_mipi_dbi.c:1024:49: warning: dubious: x | !y
CC [M] drivers/gpu/drm/drm_mipi_dbi.o
As long as buffer is consist of byte (u8) values, we may use
simple right shift and satisfy compiler. It also reduces amount of
operations needed.
