The DRM color management framework is targeting various hardware platforms and drivers. Different platforms can have different color correction and enhancement capabilities. A commom user space application can query these capabilities using the DRM property interface. Each driver can fill this property with its platform's color capabilities. This patch adds new structures in DRM layer for querying color capabilities. These structures will be used by all user space agents to configure appropriate color configurations.
