nvdimm: Use configurable ACPI IO base and size

Browse source 
This patch makes IO base and size configurable to create NPIO AML for
ACPI NFIT. Since a different architecture like AArch64 does not use
port-mapped IO, a configurable IO base is required to create correct
mapping of ACPI IO address and size.
