TGL systems have the same issue as ADL, where a large boot firmware delay is seen if USB ports are left in U3 at shutdown. So apply the XHCI_RESET_TO_DEFAULT quirk to TGL as well. The issue it fixes is a ~20s boot time delay when booting from S5. It affects TGL devices, and TGL support was added starting from v5.3.
