MDP has a new hardware block for converting mixer
output to yuv format before the data goes to the
interface block. This block will be used for enabling
yuv420 output on HDMI and writeback interfaces. In
case only one block is present, it needs to be
shared between HDMI and writeback.

When post processing(pp) blocks are udpated in mdp hardware
new functions should be added into pp driver for caching the
params required to program them. Cached params are committed
to hardware when next frame is being queued for rendering.
PP driver file is becoming huge due to addition of caching changes
for different revisions of MDP. This change moves the caching code
for upcoming mdp revisions into a separate file.

When doze mode is requested while the panel in powered off, the
panel needs to be first unblanked and then configured into low power
mode. While this sequence exists in the current implementation,
the execution sequence only calls MDP's on function while unblanking
the panel. The correct approach is to go through the full unblank
sequence which would also start the display commit thread. Without
this, screen updates while in doze mode will not work and could
lead to unexpected behaviors.
