drm/msm: update plane rotation API for kernel 4.14

This patch updates the SDE DRM driver ported from 4.9 to use the
updated DRM rotate/reflection flags, as well as the plane rotation
property access and installation.  The previous implementation
created a single bitmask property that was then attached to each
plane, and all planes were affected when this property changed.
With the new API the rotation property is created and attached
for each plane.  This allows rotation to be controlled on
individual planes but has the side-effect that the rotation
property ID will be different for each plane.
