Add of_platform_default_populate() to stratix10-svc
driver as the firmware/svc node was moved out of soc.
This fixes the failed probing of child drivers of
svc node.

I checked of_platform_populate/of_platform_bus_create() and see these
functions will not error out if some sub device registration fails. So
LGTM.
