All the cpu_is checks have been moved to dss_init_features function providing a
much more generic and cleaner interface. The OMAP version and revision specific
initializations in various functions are cleaned and the necessary data are
moved to dss_features structure which is local to dss.c.

All the values are const. So we have a const pointer dss.feat to hold
this structure. Is a separate
const char *clk_name required?

Yes, the values are const, so the pointer itself is const. However, the
chars where the pointer points are not const. So:

feat.clk_name = 1234; // this is rejected by the compiler
feat.clk_name[0] = 0; // this would be accepted
