nvdimm acpi: fix region format interface code
Per ACPI 6.2, section 5.2.25.6 and JEDEC Annex L Release 3, the current region format interface code 0x201 indicates the block addressed function interface 1, rather than a byte addressable interface. Fix it by using 0x301 which indicates the byte addressable no energy backed function interface 1. Signed-off-by: Haozhong Zhang <haozhong.zhang@intel.com> Reviewed-by: Michael S.
