ACPICA: ACPI 6.2: Add support for PinFunction() resource
ACPICA commit 6bbc6357f7061f1243601adde0ea45f7a89274e0 ACPI 6.2 introduced a new resource that is used to describe how certain pins are muxed for a device. The ASL syntax of this new resource looks like below: PinFunction(Shared, PinConfig, FunctionNumber, ResourceSource, ResourceSourceIndex, ResourceUsage, DescriptorName, VendorData) {Pin List} Which is pretty similar to GpioIo()/GpioInt() resources. Teach ACPICA about this new resource.
