bionic: Add msm_rotator.h and Update msm_mdp.h from kernel/include/linux

Kernel commit id: e5ad7f1a0a4c93eb48c970c86d76517eb73d95e1
msm_rotator is image rotator driver for MSM 7x30. Add msm_rotator.h
from kernel/include/linux to bionic.

Update msm_mdp.h to match kernel include file.

Kernel commit id: d8b302dd323abf221f5fd5355c7d8d108b169497
add 3 overlay ioctl functions, set, play and unset to allow
user applications, such as surface flinger, to utilize MDP4
overlay blending feature among video and rgb pipes.
