Ticket #1684 (closed enhancement: fixed)
WLAN to default to off on Freerunner, switchable down /sys

GTA02 WLAN is actually always on, but it takes a power and reset signal from GPIO.
Until now, machine init always powered the thing up by these, adding 300ms to early boot and causing it to eat more power for the whole session.
I already have a patch that exposes the power_on and reset GPIO same as done for bt, I will test it (particularly SDIO autodetect is a question, the code seems to be there) shortly.
The impact on userspace is going to be that dumb initscripts that expect eth0 there are going to fail now. It really needs to be done via udev, so the WLAN device can randomly appear and then get configured by NetworkManager? or whatever.
