Audio: FM and BT support, cleanup, power up/down noise removal

Add new transducer for FM to configure audio codec registers.
Add new transducer for BT to configure gpio and enable msp0 clk.
Fix noise issue at begining and end of playback/voice call.
Add platform device and platform driver to suport voltage regulator framework.
Remove allmost all of printk and use dev_err, dev_info family macros.
Correct file copyright notice.
Remove use of typedefs.
Add vibrator functionality which uses PWM source.
Add function  to configure audio codec IF1 required for FM.
