Is this con_id really needed now? Searching for "usb20_psc_clk" in your
tree results in only this one hit.

I guess multiple dev_id matches like these are another hurdle in moving
them to davinci_psc_clk_info[] table? If its too cumbersome to keep
multiple entries in the table, they can be handled as an exception at
the end of processing the table? Still they are not the norm so I hope
the normal case will still benefit.
