superio/ite/it8623e: add support for SIO chip ITE IT8623E 

This change adds basic support for the SuperIO chip ITE IT8623E.
Due to the lack of a datasheet, defaults are shown as "not available (NA)"
in superiotool's register dump. LDNs defined in it8623e.h are
definitely correct and working as expected.
