platform/surface: aggregator_registry: Make symbol 'ssam_base_hub_group' static

The sparse tool complains as follows:

drivers/platform/surface/surface_aggregator_registry.c:355:30: warning:
 symbol 'ssam_base_hub_group' was not declared. Should it be static?

This symbol is not used outside of surface_aggregator_registry.c, so this
commit marks it static.
