    src/arch/x86/acpi.c: Use correct host address width in DMAR ACPI table.
    
    The previous implementation assumed the CPU physical address size to be 40
    which is not true of all platforms. Use an existing function to obtain the
    correct CPU physical address to report in the DMAR ACPI table.
