Nico Huber b992df9891 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

Nico Huber a6a8df39e1 util/qemu: Add additional config file for QEMU/Q35
The `q35-alpine.cfg` adds a lot of PCIe devices to resemble the
topology inside an Intel Alpine Ridge Thunderbolt controller.
By no means could this be detected as such a controller. But
having a real-world example of such a topology can help to
test the allocator and other algorithms on a deeper tree.

It adds two levels of PCIe switches (`alpine-root` and
`alpine-1`), and two endpoints (a `pci-testdev` and an xHCI
controller).

It can be added to the default `q35-base.cfg` config, e.g.
with:

    $ make qemu QEMU_EXTRA_CFGS=util/qemu/q35-alpine.cfg

Martin Roth b513c53f31 util: Make sure all util dirs have description files at top level
New util directories have been added with no description.md file.
The description file for supermicro was added at a secondary level,
which doesn't help a user find the util since no path was added. Move
it up to the top level.

Nico Huber 9e20e2f158 util/qemu: Add comprehensive default config for QEMU Q35
This config tries to mimic the actual devices of a mainboard
with Intel's Q35 chipset. It provides a much better base to
test coreboot (e.g. its allocator) and payloads.

Nico Huber a08328ecff util/qemu: Add `qemu` make target
Add some mechanics to automatically have a `qemu` make target for
supported configurations. So with a QEMU target selected in Kconfig,
one would ideally only have to run `make qemu` to test things.

There are some notable variables that can be set or adapted in
`Makefile.inc` files, the make command line or the environment.

Primarily for `Makefile.inc` use:
 QEMU-y           the QEMU executable
 QEMU_CFG-y       a QEMU config that sets the available default devices,
                  used to run more comprehensive tests by default,
                  e.g. many more PCI devices

For general use:
 QEMU_ARGS        additional command line arguments (default: -serial stdio)
 QEMU_EXTRA_CFGS  additional config files that can add devices

 QEMU_CFG_ARGS    gathers config file related arguments,
                  can be used to override a default config (QEMU_CFG-y)

Examples:

  $ # Run coreboot's default config with additional command line args
  $ make qemu QEMU_ARGS="-cdrom site-local/grml64-small_2018.12.iso"

  $ # Force QEMU's built-in config
  $ make qemu QEMU_CFG_ARGS=
