IIRC the reason why this is built-in is that there are all kind of ACPI
GPIO magic happening behind the scenes on Baytrail-T based machines
(such as Asus T100) and it does not work without the GPIO driver. Some
of the stuff is done pretty early too.

I'm adding Mathias the original author of the driver if he remembers
the details better.
