ACPI NFIT enabled platforms provide media errors as absolute phyiscal
address offsets. Add an option to ndctl to display those media errors
tranlsated to region and namespace device level offsets in an "ndctl
list" listing.

Adding option for ndctl list command to show badblocks for region and
device. The device badblocks are calculated from the region badblocks.
This allows the user to provide the proper badblock offset and length
for clearing later on.

Adding option for ndctl list command to show badblocks for region and
device. The device badblocks are calculated from the region badblocks.
This allows the user to provide the proper badblock offset and length

Adding ndctl support that will allow clearing of bad blocks for a device.
Initial implementation will only support device dax devices. The ndctl
takes a device path and parameters of the starting bad block, and the number
of bad blocks to clear.

badblock coverage.
v5: Address comments from Toshi
- Made -l 0 to error out and no length means 1 block cleared.
v6: Address comments from Dan
- Fixed clear-error to be based off of device instead of region.
- Added list-errors command to ndctl

Adding list-errors command to support displaying of all badblocks in
relation to the device rather than the region. This allows the user to
know what badblocks to pass in when doing clear-error calls.
