[3/3] ASoC: omap3pandora: Convert to table based DAPM setup

Commit Message

Lars-Peter Clausen March 8, 2014, 6:16 p.m. UTC

Use table based setup to register the controls and DAPM widgets and routes. This
on one hand makes the code a bit shorter and cleaner and on the other hand the
board level DAPM elements get registered in the card's DAPM context rather than
in the CODEC's DAPM context.
