sb/intel/common/pciehp: Replace HP dummy device with common code

Use the common PCIEXP_HOTPLUG code to generate a dummy device for PCIe
ports supporting hotplug. This allows to have control over how much
resources are allocated to hotplug ports.

Tested on thinkpad X220: now hotplugging a dGPU via the expresscard
slot sometimes works.
