ASoC: twl6040: Earphone path correction
Fix the DAPM routing for the earphone path. Convert the DAPM_SWITCH_E to DAPM_OUT_DRV_E, so we can have correct power up, and down sequence for EP. Introduce mute control (Earphone Playback Switch) for users to enable/disable the EP path. Note: the EP does not have it's own dedicated DAC. EP is connected to HSL DAC.
