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.
