The requested gpio pin must has the func_pin_mux field set
to GPIO function by BIOS/FW in advanced. Else, the gpio pin
request would fail. This is to ensure that we do not expose
any gpio pins which shall be used for alternate functions,
for eg: wakeup pin, I/O interfaces for LPSS, etc.

Patch applied with Darren's ACK.
This confirms my suspicion that you will not be able to
hide the pin control interface side of this hardware forever. ;-)
Mika/Mathias: any comments?
