ALSA: ASoC: Add AK4535 driver
The AK4535 codec is included in some HP iPAQ systems. This driver was originally written by Richard Purdie and with some bug fixes from Milan Plzik. While out of tree it has also had some mechanical updates for new APIs and current best practices from Liam Girdwood, Graeme Gregory and Mark Brown.
