util/qemu: Revise q35 configs
Add an NVMe drive and be more conservative with hotplug-capable PCIe
ports. QEMU treats everything as hotpluggable by default, so devices
can be added at runtime. However, this leads to unrealistic resource
allocations with PCIEXP_HOTPLUG enabled.
Tested recent allocator changes with QEMU/Q35 config and:
$ make qemu QEMU_EXTRA_CFGS=util/qemu/q35-alpine.cfg
