The Observa VH4032N has some troubles related to the pinctrl since the adoption
of this driver:
- missing pinctrl avoiding to operate the wifi correctly
- missing pinctrls avoiding the LAN LEDs to be hardware controlled
- the GPIO hog doesn't work, and as a result of this the onboard USB HUB
isn't
pulled out of reset. Also the GPIO chip fails to register and the LEDs
won't work.
Fix it by adding the missing pincontrols. And workaround the USB HUB issue
by pulling it out of reset using a fake LED on the GPIO pin.
Leave the GPIO hog code disabled until this feature works with the
brcm63xx GPIO pinctrl.
