intel_sst: rework jack implementation

This patch fixes the below issues w.r.t jack implementation

a) The current jack implementation in driver is implemented
   in intelmid.c. It has moved to vendor files for better managebility
b) Cleaned up jack reporting per upstream comments
c) Implemented jack for msic, added code to read adc and deduce jack
   type based on mic bias
d) Support detection of american headset
