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: 4e88d4c08301 ("usb: add a flag to skip PHY initialization to struct usb_hcd")
Fixes: 178a0bce05cb ("usb: core: hcd: integrate the PHY wrapper into the HCD core")
