ACPI: Add functions for DMAR I/O-APIC and HPET entries
Refactor acpi_create_dmar_drhd_ds_pci() and add similar functions for
I/O-APICs and MSI capable HPETs. We violate the spec [1] here, which
talks about 16-bit source-ids spread over start_bus and path entries.
Intel actually uses bus/dev/fn identification for those devices too,
and so do we.
