pyramid: remove unused board
HTC 8X60 AUDIO:
Added htc_acoustic_8x60
Added a new CONFIG flag: CONFIG_MSM8X60_AUDIO_1X that compiles htc version of qdsp6v2 (qdsp6v2_1x)
mpp: modify mpp helper not to use specific pm8901/pm8058. Use pm8xxx_config instead, as pm8xxx do the job all alone. Updated files that needed this.
pyramid: enabled sound
