ACPICA: ACPI 6.2: Add support for PinGroupFunction() resource

ACPICA commit bd9a745749eac7137cd23085e6bdeb322de14ea2

PinGroupFunction() is a new resource introduced with ACPI 6.2. It is
used with PinGroup() to configure specific mode for a set of pins
exposed by a GPIO controller.

The format of the resource is:

  PinGroupFunction (Shared/Exclusive, FunctionNumber, ResourceSource,
                    ResourceSourceIndex, ResourceSourceLabel,
                    ResourceUsage, DescriptorName, VendorData)

The resource_source and ResourceSourceLabel fields are used to specify
the PinGroup() resource referenced by PinGroupFunction().

  Device (GPIO)
  {
      Name (_CRS, ResourceTemplate () {
          PinGroup ("group1") {2, 3}
          PinGroup ("group2") {4, 5}
          ...
      })
  }

  Device (I2C)
  {
      Name (_CRS, ResourceTemplate () {
          PinGroupFunction (Exclusive, 6, "^GPIO", 0, "mygroup2")
      })
  }

In the above example the PinGroupFunction() references the second
PinGroup() resource (using label "mygroup2" and configures pins 4 and 5
into mode 6.
