drm/drm_ras: Add drm_ras netlink error event

Browse source 
Define a new netlink event 'error-event' and a new multicast group
'error-report' in drm_ras. Each event contains device name, node and
error information to identify the error triggering the event.

Add drm_ras_nl_error_event() to trigger an event from the driver.
Userspace must subscribe to 'error-report' to receive 'error-event'
notifications.

Usage:

$ sudo ynl --family drm_ras --subscribe error-report
