superio/winbond/w83667hg-a: Add support for W83667HG-A 

The KGPE-D16 and KCMA-D8 use a Winbond W83667HG-A SuperIO.  While
the Nuvoton NCT5572D is effectively the same core, and a close
enough match to get things working initially, the W83667HG-A
has a different LDN mapping and several extra features that
require a separate support driver.

Clone the Nuvoton NCT5572D and modify according to the W83667HG-A
datasheet, version 1.4.
