Subject: [PATCH v2 1/4] Input: i8042: Swap old quirk combination with new quirk for NHxxRZQ

Some older Clevo barebones have problems like no or laggy keyboard after
resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE
quirk.

With the old i8042 quirks this devices keyboard is sometimes laggy after
resume. With the new quirk this issue doesn't happen.
