ASoC: machine support for Toshiba e740 PDA

This patch provides suupport for the wm9705 AC97 codec on the Toshiba e740.

Note:
The e740 has a hard headphone switch that turns the speaker off and is not
software detectable or controlable. Also both headphone and speaker amps
share a common output enable.
