Now that acpiphp_check_bridge() always enumerates devices behind the
bridge, there is no need to do that for each sub-bridge anymore like it is
done in the current ACPI-based PCI hotplug code. Given this we don't need
check_sub_bridges() anymore and can drop the function completely.
This also simplifies the ACPIPHP code a bit.
