Move the two function pointers to a new dss_ops structure. This will
allow merging the dss_features and omap_dss_features structures without
having to expose the DPI source selection and LCD clock muxing functions
in header files.

Changes since v2:
- Correctly use dss_ops_omap4 instead of dss_ops_dra7 for OMAP44xx
