acpi: Add support for generating ACPI _UPC

Hardware / Coreboot - Duncan Laurie [google.com] - 11 May 2018 09:00 EDT

This commit adds support for writing ACPI _UPC structures that help describe USB ports for the OS.

This is a simple structure format which indicates what type of port it is and whether it is connectable. It should be paired with an ACPI _PLD structure to define USB ports for the OS.
