ARM: pxa: eseries: use gpio lookup for audio

The three eseries machines have very similar drivers for audio, all
using the mach/eseries-gpio.h header for finding the gpio numbers.

Change these to use gpio descriptors to avoid the header file
dependency.

I convert the _OFF gpio numbers into GPIO_ACTIVE_LOW ones for
consistency here.
