Request the GPIO by index through the consumer API. For now, use a quick
hack to store the already requested ones, simply because I have no idea
whether this actually works or not, and I have no way to test it.

Would be cool if someone dumped out the relevant ACPI table(s) on
a machine that needs this stuff, so that we can see if things look
sane on that level.
