SuperIO
This plugin enumerates the various ITE85* SuperIO embedded controller ICs found
in many laptops. Vendors wanting to expose the SuperIO functionality will need
to add a HwId quirk entry to superio.quirk.
See https://en.wikipedia.org/wiki/Super_I/O for more details about SuperIO and what the EC actually does.

SuperIO-$(chipset), for exampleSuperIO-IT8512
Vendor ID Security
The vendor ID is set from the baseboard vendor, for example DMI:Star Labs

This plugin requires access to raw system memory via inb/outb.
