arch/x86/acpi: Add DMAR RMRR helper functions

Add DMAR RMRR table entry and helper functions, using the existing
DRHD functions as a model. As the DRHD device scope (DS) functions
aren't DRHD-specific, genericize them to be used with RMRR tables as
well. Correct DRHD bar size to match table entry in creator function,
as noted in comments from patchset below.
