OMAPDSS: Add overlay manager width and height limits as a dispc feature 

The overlay manager width and height vary in OMAP5 from previous OMAPs
in terms of maximum limit and register field positions. Add parameters
in dispc_features for these. Also remove params related to manager width
and height from dss_features, as we want to maintain a feature list for
individual IPs.
