Input: atkbd - skip deactivate for Xiaomi Book Pro 14's internal keyboard

Browse Source 
The internal keyboard of the Xiaomi Book Pro 14 does not work unless
atkbd skips deactivating it at the end of atkbd_probe().

Using 'i8042.dumbkbd=1' also makes the keyboard work, but then the driver
never writes to the keyboard at all, so the Caps Lock LED is lost. The
atkbd_deactivate_fixup quirk fixes both without a boot parameter.
