What exactly do you mean by not loading stratix10-svc driver ?
This patch doesn't change that part, the driver should still get loaded.
The change may affect probing part if for some reason the devices for
nodes under firmware are not populated which I still can't understand.

Do you see any change under i/sys/devices/platform/firmware\:* with
and without this change ?

Lots of drivers removed the code similar to this patch after the Commit
3aa0582fdb82 ("of: platform: populate /firmware/ node from
of_platform_default_populate_init()") and continue to work fine. I am
interested to see what is different in stratix10-svc.
