Title: msm_fb: Fix blending logic for formats with per-pixel alpha

Currently if a layer with per-pixel alpha (eg. RGBA) is fed
for composition with z-order as zero (FG), per-pixel alpha
blending is applied along with the BG frame present on frame
buffer and hence we see the previous frame on the panel. Hence,
apply constant alpha blending if these formats are fed as FG.
