From: Shashank Sharma <shashank.sharma@xxxxxxxxx>
Color manager's plane level correction properties are
registered as plane property. So its required to have a
.set_property function in plane functions.
This patch adds:
1. A .set_property function for intel_plane, intel_plane_set_property
which checks if a plane property is of type color property, it
calls color manager's plane level set_property handler function.
2. A intel_clrmgr_set_plane_property, which will extract the data
to be set, and then pass it to appropriate set_property function
