msm: mdss: Fix panel orientation handling for split displays

Browse source 
For split display panels, when panel has 180 flip or HFLIP,
the source layers needs to be swapped instead of the mixers.
SDM will take care of the source swap and rectangle
recalculations.
This change is to remove the mixer swap, and to expose the panel
flip property through sysfs, so that SDM can flip the source
layers to maintain pipe priority.
