Subject: [PATCH mlx5-next 3/4] IB/mlx5: Add legacy events to DEVX list

From: Yishai Hadas <yishaih@...lanox.com>

Add two events that were defined in the device specification but were
not exposed in the driver list.

Post this patch those events can be read over the DEVX events interface
once be reported by the firmware.
