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.
