Add cs42l43 PC focused SoundWire CODEC

Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:

This patch chain adds support for the Cirrus Logic cs42l43 PC focused
SoundWire CODEC. The chain is currently based of Lee's for-mfd-next
branch.

This series is mostly just a resend keeping pace with the kernel under
it, except for a minor fixup in the ASoC stuff.

Thanks,
Charles
