OMAP4 panda board specific device tree node is included.
In OMAP4 panda board, the port 1 is used in ULPI PHY mode.
The port 1 is connected to a on board hub with ethernet
interface.
TODO:
The clock bindings are not yet avilable for OMAP4.
hence , USB hub specific clocks are exported as device tree string
paramters.
Will be changed to use the clock bindings later
