coil: remove unused driver code

The extra driver code uses coil terms we're removing, but we don't use
it in platform/cr50. Remove the code instead of replacing the terms.

Cr50 boards only use inaxx code. The host uses thermister code. Remove
everythinge else.

We can cleanup the tests that run the thermsiter code later.

BUG=b:175244613
TEST=make buildall -j
