This is a simple approach to prevent scattered cpu_is_omapxxxx checks in DSS2 by bringing all omap version specific DSS features/values to one single place, initialize them and expose a set of functions to DSS2 driver files which return the value/existance of a feature. This method provides the following: -A set of functions which give the value of a feature. -Functions which add and return the start and end bits of a register field which varies across omaps. -A function which checks if a DSS2 feature exists or not on the present omap (omap_dss_has_feature) Whenever a new DSS feature is introduced, its value/existance is specified for all omaps in omap_dss_feature_init(). This patch also fills up a minimal list of features in omap_dss_features_init(). The second patch in the series makes use of dss_features to remove some of the existing omapxxxx checks.
