Drop the _CCA requirement once the updated ACPI spec is published

[vlsunil]

I think RISC-V is similar to Intel in this regard than ARM. If agreed, it is better to create an ECR to update as "On Intel and RISC-V platforms, if the _CCA object is not supplied, the OSPM will assume the devices are hardware cache coherent. ". With that, the requirement can be removed from BRS?

ASWG Mantis 2407 does this already (https://mantis.uefi.org/mantis/view.php?id=2407):

"On Intel and RISC-V platforms, if the _CCA object is not supplied, the OSPM will assume the devices are hardware cache coherent."

Once the updated ACPI spec is published, the _CCA requirement can be dropped from BRS.
