The usb_add_hcd() will call phy_{get,init,power_on}() if hcd->phy is not set.
After the usb_add_hcd() call phy_power_on(), it keeps until usb_remove_hcd().
And then, even if the system turns suspend, the usb core keeps the phy power.
I think that each host driver should handle the phy power. So, this patch
sets hcd->phy before usb_add_hcd() to avoid phy_get() in usb_add_hcd().
I'm not sure that this is a suitable way. (e.g. usb_add_hcd() should not call
phy_get()?) So, I marked "RFC" into this patch set.
