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 palette color capabilities. This patch adds new structure in DRM layer for querying palette color capabilities. This structure will be used by all user space agents to configure appropriate color configurations.
