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.

[1] Intel Virtualization Technology for Directed I/O
        Architecture Specification
