SOC dependent PHY driver actually deals with the PHY interface programming.
e.g. please see code present in tegra2_usb_driver.c.

As PHY related bugs got fixed across different set of SOCs apart from
adding few features, wanted to separate this out from common PHY
functionality. This will help us in adding support for different SOCs with
minimum set of changes.
