usb: host: xhci-plat: get the usb3 phy for shared_hcd

Browse Source 
This patch tries to get the USB3 PHY using, and associates
the XHCI shared_hcd device with it.

With this patch, the USB HUB core driver can do USB PHY
operations base on USB PHY framework, e.g. call usb_phy_
notify_connect() or usb_phy_notify_disconnect() to notify
USB PHY driver to do soft connect or soft disconnect.
