usb: dwc3: disable USB core PHY management

Browse Source 
commit 6000b8d900cd5f52fbcd0776d0cc396e88c8c2ea upstream.

The dwc3 driver manages its PHYs itself so the USB core PHY management
needs to be disabled.

Use the struct xhci_plat_priv hack added by commits 46034a999c07 ("usb:
host: xhci-plat: add platform data support") and f768e718911e ("usb:
host: xhci-plat: add priv quirk for skip PHY initialization") to
propagate the setting for now.

Fixes: 4e88d4c083 ("usb: add a flag to skip PHY initialization to struct usb_hcd")
Fixes: 178a0bce05 ("usb: core: hcd: integrate the PHY wrapper into the HCD core")
