PCI: pcie: Ensure hotplug ports have a minimum number of resources
In general a BIOS may goof or we may hotplug in a hotplug controller. In either case the kernel needs to reserve resources for plugging in more devices in the future instead of creating a minimal resource assignment. We already do this for cardbus bridges I am just adding a variant for pcie bridges. v2: Make testing for pcie hotplug bridges based on a flag. So far we only set the flag for pcie but a header_quirk could easily be added for the non-standard pci hotplug bridges. Signed-off-by: NEric W.
