[v4,0/6] arm/komeda: Add side_by_side support

Message

Hi: All

Komeda HW (two pipelines) can work on side by side mode, which splits the
internal display processing to two halves (LEFT/RIGHT) and handle them by
two pipelines separately and simultaneously.
And since one single pipeline only handles the half display frame, so the
main engine clock requirement can also be halved.

The data flow of side_by_side as blow:

 slave.layer0 ->\                  /-> slave.wb_layer -> mem.fb.right_part
     ...         -> slave.compiz ->
 slave.layer3 ->/                  \-> slave.improcessor->
                                                          \   /-> output-link0
 master.layer0 ->\                   /-> master.improcessor ->\-> output-link1
     ...          -> master.compiz ->
 master.layer3 ->/                   \-> master.wb_layer -> mem.fb.left_part

v3: Rebase
