Add 2 software manage quirk properties (xhci-missing-cas-quirk and
xhci-skip-phy-init-quirk) for xhci host.

dwc3 driver have PHY management to cover both device and host mode, so add
xhci-skip-phy-init-quirk to skip PHY management from HCD core.

Cold Attach Status (CAS) bit can't be set at i.MX8MP after resume from
suspend state. So set xhci-missing-cas-quirk.

You're missing changes from v3 to v4

This looks very different than the previous version. Did you review the
change before rebase? We should already do of_get_compatible_child() a
few lines above.

Please remove the Acked-by for now.
