From: Mika Westerberg <mika.westerberg@xxxxxxxxxxxxxxx>
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 (ACPIPHP) code.
Given this we don't need check_sub_bridges() anymore, so drop that
function completely.
This also simplifies the ACPIPHP code a bit.
