intel/skylake: Add support for IV feedback loop capture blob 

SSM4567 smart speaker needs Current and Voltage sensing to be
captured and reported to the algorithm.
This needs 4 CH capture blob.

BUG=chrome-os-partner:48625
BRANCH=none
TEST=Built and booted. Verified CBFS locates
     the blob.
CQ-DEPEND=CL:*242635
