acpi/nfit: Update nfit driver to comply with ACPI 6.1
ACPI 6.1, Table 5-133, updates NVDIMM Control Region Structure as follows. - Valid Fields, Manufacturing Location, and Manufacturing Date are added from reserved range. No change in the structure size. - IDs (SPD values) are stored as arrays of bytes (i.e. big-endian format). The spec clarifies that they need to be represented as arrays of bytes as well. This patch makes the following changes to support this update. - Change the NFIT driver to show SPD ID values in big-endian format. - Change sprintf format to use "0x" instead of "#" since "%#02x" does not prepend '0'. link: http://www.uefi.org/sites/default/files/resources/ACPI_6_1.pdf Signed-off-by: Toshi Kani <toshi.kani@hpe.com> Cc: Rafael J.
