superio/common: Add ssdtgen for generic SuperIOs
Add a generic SuperIO ACPI generator, dropping the need to include
additional code in DSDT for SuperIO.
It generates a device HID based on the decoded I/O range.
Tested on Supermicro X11SSH-TF using AST2400.
The SSDT contains no errors and all devices are present.
Possible TODOs:
* Add "enter config" and "exit config" bytes
* Generate support methods to enter and exit config mode
* Generate support methods to query, change or disable current
resource settings on specific LDNs
