atkbdc - Change default to still attach PS2 controller even if FADT says don't

* Temporary workaround, disable commit 131acb0380e93664 by default.
  It can be enabled again with a tunable in /boot/loader.conf:

  hw.acpi.fadt_8042_nolegacy=1

* Should work around several bug reports of the keyboard not working
  in 5.4.
