We expose the various error counters supported on a hardware via genl
subsystem through the registered commands to userspace.
The DRM_CMD_QUERY lists the error names with config id, DRM_CMD_READ_ONE
returns the counter value for the requested config id and the
DRM_CMD_READ_ALL list the counters for all errors along with their names
and config ids.
