hardware/t100ha: Add patch for SST sound

This is essentially a backport of @plbossart's "experimental/codecs"
branch against Linux 4.9.

The original repository can be found at:

https://github.com/plbossart/sound/commits/experimental/codecs

Thanks to him for doing a lot of work on getting sound working for these
CherryTrail devices.
