sunxi: usb: Move setup of host controller clocks to the host controller drivers
The sunxi "usbc" code is mostly about phy setup, but currently also sets up
the host controller clocks, which is something which really belongs in the
host controller drivers, so move it there.
This is a preparation patch for moving the sunxi ehci code to the driver
model and for adding ohci support.
