drm/drm_ras: Add clear-error-counter netlink command to drm_ras
Introduce a new 'clear-error-counter' drm_ras command to reset the counter
value for a specific error counter of a given node.
The command is a 'do' netlink request with 'node-id' and 'error-id'
as parameters with no response payload.
Usage:
$ sudo ynl --family drm_ras --do clear-error-counter --json \
'{"node-id":1, "error-id":1}'
None
