x86, reboot: Acer Aspire One A110 reboot quirk

Since git commit
  660e34cebf0a11d54f2d5dd8838607452355f321 x86: reorder reboot method
  preferences,
my Acer Aspire One hangs on reboot.  It appears that its ACPI method
for rebooting is broken.  The attached patch adds a quirk so that the
machine will reboot via the BIOS.

[ hpa: verified that the ACPI control on this machine is just plain broken. ]
