superio/ite/it8720f: add new IT8720F Super I/O

This device is extremely similar to the IT8718F, so support is based on
existing support for the IT8718F. The CIR device is only detected by
Linux/Windows from the ACPI tables, so ACPI support is extended from the
IT8783E/F (for ACPI). This Super I/O is used on the Foxconn G41S-K.

Tested, working:
* Serial port 1
* Environment controller
  - Temperature monitoring
  - Voltage monitoring
  - Fan control (automatic and manual)
* PS/2 keyboard and mouse

Appears, OS driver loads, but otherwise untested:
* Serial port 2
* Consumer IR

Untested:
* Floppy controller
* Parallel port
* GPIO
