tegra-alt: mvc: Updated mixer controls

Browse Source 
Following updates:
 - "input bit format" ctl to set RX CIF bit-width
 - 100x scaling to "Vol" ctl for more granularity
 - Fixes in mixer ctl "get" functions so that current value is read
 - Fix in "Curve Type" ctl so that default volume gets set
