[RFC PATCH 3/6] usb: otg: utils: change the phy lib to support multiple PHYs of same type

Wed Jan 16 10:00:59 EST 2013
In order to add support for multipe PHY's of the same type, the API's
for adding PHY and getting PHY has been changed. Now the binding
information of the PHY and controller should be done in platform file
using usb_bind_phy API. And for getting a PHY, the device pointer of the
USB controller and an index should be passed. Based on the binding
information that is added in the platform file, get_phy will return the
approappropriate PHY.
