Subject: [PATCH] drm/msm/mdp5: Add hflip/vflip support to MDP5 planes (v2)

MDP5 SSPPs can flip the input source horizontally or vertically.
This change is to add this support to MDP5 planes.
v1: Initial change
v2: Use existing "rotation" property instead of creating msm specific
properties. In order to be compatiable with legacy non-atomic
set_property, switch to drm_atomic_helper_plane_set_property
helper function.
