ARM: pxa: poodle: use platform data for poodle asoc driver

The poodle audio driver shows its age by using a custom
gpio api for the "locomo" support chip.

In a perfect world, this would get converted to use gpiolib
and a gpio lookup table.

As the world is not perfect, just pass all the required data
in a custom platform_data structure. to avoid the globally
visible mach/poodle.h header.
