google/rambi: add board-specific USB port info
Add capability and location data for USB ports/devices via
_PLD and _UPC ACPI methods, which is utilized by Windows and
required by macOS.
Each rambi variant has a different USB port config.
Port data currently available for only candy and squawks;
other variants to be added once data obtained.
