superio/winbond/wpcd376i: Resurrect the driver
This SuperIO chip is used on the Intel DQ45EK mainboard. Restore the driver that was deleted in commit d3a1a4171ee9 ("src/superio: Remove unused superio chips"). Changes from the previous version include: - Replacing the early serial implementation with Winbond common code, - Replacing the license boilerplate with SPDX headers, and - Removing unnecessary header file references.
