Peter Ujfalusi 39646871a4 ASoC: tpa6130a2: Replace DAPM code with direct interface
The use of DAPM widgets, and extra routing can cause ordering
problems in the system.
Machine drivers should use the exported direct interface with
SND_SOC_DAPM_HP's event callback to manage the state of the
amplifier.
