This patch adds the SMBus Device IDs for the Intel Wellsburg PCH
Signed-off-by: James Ralston <james.d.ralston@xxxxxxxxx>
---
Change notes for v3:
*The additional Device IDs added in v2 are for the SMBus MS Unit and are referred to as SMBus_MS*. These devices are similar to the Patsburg IDF in functionality, however they are referred to as MS Unit devices in the External Design Specification.
