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

Browse source 
ACPICA commit 08b83591c0db751769d61fa889f4f50f575aeffb

PinGroupConfig() is analogous to PinGroupFunction() but instead of mode
(muxing), it is used to apply specific fine-grained configuration to a
set of referenced pins.

The format of this new resource is:

  PinGroupConfig (Shared/Exclusive, PinConfigType, PinConfigValue,
                  ResourceSource, ResourceSourceIndex, ResourceSourceLabel,
                  ResourceUsage, DescriptorName, VendorData)

The PinConfigType/PinConfigValue are the same used by PinConfig()
resource.

Here also the combination of ResourceSource and ResourceSourceLabel is
used to specify the PinGroup() this resource refers to.
