msm: mdss: add generating 128 bytes of DSC PPS
Add generating 128 bytes of DSC PPS (picture parameters set) base on specified DSC picture width/height and slice width/height. Send 128 bytes PPS stream to configure and enable panel's DSC. Change-Id: I3f2fcb7098023b7d27ef85392e4d5f36bf189d1b Signed-off-by: Kuogee Hsieh <khsieh@codeaurora.org>
