Codec specific metadata is sent only for first stream in gapless
playback. This causes incorrect configuration to be set for second
stream and distortions are observed due to framedrops in adsp.
Add support to send codec specific format during start of
next stream in gapless.
Add bit rate to wma codec data structure as it can vary between
streams in gapless.

This commit adds hwdep interface for codec calibration.
currently codec driver uses request_firmware to get calibration data
but as this firmware file is also written by userspace process after
bootup, it is not recommended to use request_firmware. ALSA core
provides mechanism to get hardware dependent data using hwdep nodes.
Codec will use aforementioned nodes to get calibration data from
userspace.

- mixer_ctl_set() function is limiting the volume level
to particular range. This results in incorrect initial
volume setting for that device.
- In USB mixer while calculating the dBmin/dBmax values
resolution factor is hardcoded to 256 which results in
populating the wrong values for dBmin/dBmax.
- Fix is to use appropriate resolution factor while
