ASoC: s6105 IP camera machine specific ASoC code

This patch adds machine specific code for the audio part of the Stretch
s6105 IP camera reference design.

The device uses the tlv320aic31(01) codec to generate the clock for
both I2S ports of the soc. While the master clock is generated by a
configurable PLL chip, the code assumes the factory default settings.

An additional kcontrol has been added to handle the special routing of
the board, connecting both HPLCOM and HPROUT to the same pin of the audio
jack. One of these should always be switched off.
