disp: msm: sde: add sys cache usage for static image

Browse Source 
Store full or partial static image in system cache (L3 cache)
for video mode primary display. Added additional commit to
crtc commit thread to transition to read cache state.
The change also updates llcc APIs to support generic functionality.
