Hans de Goede e13afeef6f sunxi: usb: Do not call phy_probe from hcd code
The 2/3 usb-phys on the sunxi SoCs are really a single separate functional
block, and are modelled as such in devicetree. So once we've moved all the
sunxi usb code to the driver-model then phy_probe will be called once
for the entire block from the driver-model enumeration code.

Move to this now as this also avoids problems with phy_probe being called
multiple times once we introduce ohci support. This also allows us to get rid
of the sunxi_usb_phy_enabled_count variable as phy_probe now is guaranteed
to be called only once.

Since we're effectively rewriting the probe / remove functions, move them
to the end of the file while we are at it, as that is the most logical place
for them.
