ACPI / x86: Add KIOX000A accelerometer on GPD win to always_present_ids array

The GPD win BIOS dated 20170320 has disabled the accelerometer, the
drivers sometimes cause crashes under Windows and this is how the
manufacturer has solved this :|

I see no other way to keep the accelerometer working under Windows then
adding it to the always_present_ids array.
