ASoC: Last minute fix for v4.0

Browse Source 
This patch backs out a change that came in during the merge window which
 selects a configuration for GPIO4 on pcm512x CODECs that may not be
 suitable for all systems using the device.  Changes for v4.1 will make
 this properly configurable but for now it's safest to revert to the
 v3.19 behaviour and leave the pin configuration alone.
 
 Sorry for sending this direct at the last minute but due to the GPIO
 misuse it'd be really good to get it in the release and I'd not realised
 it hadn't been sent yet - between some travel, a job change and other
 non-urgent fixes coming in I'd lost track of the urgency.  It's been in
 -next for several weeks now, is isolated to the driver and fairly clear
 to inspection.
