[ALSA] ASoC: Add UDA1380 driver

The UDA1380 codec is used by the HTC Magician and a number of Samsung
reference boards.

This driver has had a long out of tree history, having originally been
written by Giorgio Padrin and converted to ASoC by Richard Purdie.
Since conversion to ASoC most of the work on the driver has been done by
Philipp Zabel with some review and updates for new APIs by Liam Girdwood
and Mark Brown.
