device/Kconfig: Reduce PCIe hotplug bus numbers and IO resources

The rationale behind this change is that multiple nested bridges using a
lot of bus numbers and IO resources is not likely to be a common hotplug
setup. When there is a large amount of hotplug ports using 32
subordinate busses results in boot failures (e.g. make qemu). 8K IO
busses for hotplug devices is also excessive in most use cases when only
64K is available in total (again make qemu results in failure to
allocate resources but does boot to payload).
