rdev will be destroyed and recreated during the FW error
recovery scenarios. So to keep the state, if any, use an
en_info structure which gets created/freed based on auxiliary
device initialization/de-initialization.

Adding and removing device need to be handled from multiple contexts
when Firmware error recovery is supported. So group all the add and remove
operations to add_device and remove_device function.

If the FW crashes, L2 driver gets notified and it notifies
the RoCE driver. Currently driver doesn't re-initialize the
device. Add support for re-initialize the RoCE device.
RoCE device is removed and re-attached in the ulp_stop and
ulp_start respectively. The recovery logic expects the RoCE
driver to be registered with L2 driver while its being removed.
So the driver avoids unregistering with L2 driver in the
recovery path.
