mdss: msm: Add support for gamut map enable

Browse source 
Non-uniform mapping mode is configurable parameter exposed by MDP.
Driver should provide the option to gamut clients to configure the
mapping. Change updates the interface to expose the parameter and
programs the gamut registers based on user setting.
