Adrian Salido-Moreno 1d20d0c9d4 liboverlay: fix mdp and rotator color formats 
MDP color formats have been changed to match the actual input format.
Also rotator will now provide the dst format instead of maintaining
local mapping.

CRs-fixed: 339114,337040
(cherry picked from commit f8c2fe0c78d27f9292e5bb9948db11c72446dc55)
