msm_fb: display: add mixer1 writeback buf init call

mdp4_init_writeback_buf call is missing for mixer1 interface. And
blt_addr should be nulled when dtv interface is initialized,
otherwise, mixer1 writeback mode may be false enabled which causes
system crashes or garbage display on TV.

msm_fb: display: Fix color swap issues in MDP4 and Rotator drivers

Many of MDP input formats don't have correct unpack pattern, so image
displayed on screen is not in the actual format set. Also,Some rotator
output formats differ from input, these mappings used to be handled in
userspace, but to avoid issues this is now done in driver. For YCrCb planar
inputs chrominance order is dependent on rotator hardware version. Add
hardware check to swap Cb and Cr for 7x30 and 8x60 rotators.

msm_fb: display: remove mdp writeback2 overlay kickoff waiting

Before overlay2 kickoff, there is already a dma busy waiting, so once

if there is another request while ovlay2 is still busy, dma busy can
take care of it.

msm_fb: display: add dtv wait for vsync when in blt mode

Currently dtv is waiting for overlay done when in blt mode. When dtv
frame rate is low, this return may be too soon. So before dmae
finishes updating buffer, the buffer may be overwritten by userspace.
Add dtv wait4vsync after overlay done to lock the buffer untill the
next vsync to avoid tearing or flicking.
