[PATCH] usb: phy: generic: re-factor the way we find out about our resources

[Felipe Balbi <balbi@xxxxxx>]

instead of having each user of generic phy find
out about its own resources and pass it to the
core layer, have th core layer itself figure that
out. It's as simple as moving a piece of code
around.
