usb: dwc3: imx8mp: add 2 software managed quirk properties for host mode

Browse Source 
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.
