[05/22] drm: Add get property support for color manager

Commit Message

Sharma, Shashank Oct. 9, 2015, 7:28 p.m. UTC

As per the DRM get_property implementation for a blob, framework
is supposed to return the blob_id to the caller. All the color
management blobs are saved in CRTC state during the set call.

This patch adds get_property support for color management
properties, by referring to the existing blob for the property
and passing its blob_id.
