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.
