ipq40xx: add PoE passthrough GPIO

Browse Source 
Add the GPIO pin of the PoE passthrough switch on the Aruba AP-303H.
Power is activated when the pin is low. It enables a PSE chip, so power
is only supplied to downstream devices when they are 802.3af/at
compliant devices.

Ensure you use a sufficient power supply when chaining a consuming
device after the AP.
