drm/omap: Use per-plane rotation property

The global mode_config.rotation_property is going away, switch over to
per-plane rotation_property.

Not sure I got the annoying crtc rotation_property handling right.
Might work, or migth not.

v2: Drop the BIT()
    Don't create rotation property twice for each primary plane
