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().
Changes from v1 (as RFC):
- Fix the usage condition about priv->phys[].
- Remove RFC.
