ACPICA: Allow PCC Data Type in MCTP resource.
ACPICA commit f0776a465cc2c20393bec534c16bdee4a78f7bb7
explicitly allow QWord address space description type
to be 0xA to indicate it refers to a Platform
Communication channel
IAW ACPI_ECR_PCC_DESCRIPTORS_CF_V2
https://bugzilla.tianocore.org/show_bug.cgi?id=4594
An entity in a DSDT or in SSDTs that requires
a platform communication channel table (PCCT) entry
to communicate with a remote service will have a single
value that is the index of the entry in the PCCT.
This data type with have a resource_type value of 0xA.
This value indicates that the type shares the same
footprint as a Dword_space section.
