From: Arnd Bergmann arnd@arndb.de
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.
