commit fed70b61ef2c0aed54456db3d485b215f6cc3209 upstream.
ADL-N systems have the same issue as ADL-P, 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 ADL-N as well.
This patch depends on commit 34cd2db408d5 ("xhci: Add quirk to reset host back to default state at shutdown").
The issue it fixes is a ~20s boot time delay when booting from S5. It affects ADL-N devices, and ADL-N support was added starting from v5.16.
