superio/nuvoton/npcd378: Switch to superio/common

Replace DSDT ACPI code and DSDT injection with a SSDT only solution.

The current implementation shows some issues on current Linux, which
might be due to external ACPI objects, which are then injected into
DSDT or the fact that those objects only use 3 characters.

Replace all the DSDT code with an SSDT generator.

Tested on HP Z220:
Boots into Linux with no ACPI errors. The SSDT can be disassembled.
