According to specs SSC is enabled during port clock programming based on
below conditions:
-if uhbr 10 or uhbr 20 enable ssc regardless of what display controller
asks of us
-if ubhr 13.5 or legacy rates enable ssc if required.
Currently these conditions are not exactly followed this patch series
fixes that.
One more thing this patch addresses is how SSC was not enabled for c20
PHY at all because ssc_enabled variable is never set for c20 PHY.
