acpi/nfit: Add support of NVDIMM memory error notification in ACPI 6.2
ACPI 6.2 defines a new ACPI notification value to NVDIMM Root Device
in Table 5-169.
0x81 Unconsumed Uncorrectable Memory Error Detected
Used to pro-actively notify OSPM of uncorrectable memory errors
detected (for example a memory scrubbing engine that continuously
scans the NVDIMMs memory). This is an optional notification. Only
locations that were mapped in to SPA by the platform will generate
a notification.
Add support of this notification value by initiating an ARS scan. This
will find new error locations and add their badblocks information.
