ACPI 6.2a provides an NFIT sub-table that informs if the platform has
auto CPU flush and memory flush on unexpected power loss events. This series
propogates those attributes to nd_region and add sysfs attribute to show
those capabilities.
v5:
Fix value of mask in nfit_test.
v4:
Fixed typos and added Reviewed-by tags from Ross.
v3:
Addressed Ross's comments
- fixed mask calculation for platform cap
- fixed nfit_test nfit_buf size calcuation
- fixed offset for test data structure
v2:
Per Dan's comments
- Added ADR cap flags propogation
- Added sysfs attribute
