Subject: [PATCH v2 2/4] Input: i8042: Add required quirks for missing old boardnames

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.

The PB71RD keyboard is sometimes laggy after resume and the PC70DR, PB51RF,
P640RE, and PCX0DX_GN20 keyboard is sometimes unresponsive after resume.
This quirk fixes that.
