Tobias WaldekranzandJoachim Wiberg f572f173da qemu: Refine serial setup
- When running with full disk emulation (via GRUB on x86, or U-Boot on
  aarch64), there's no way for us to influence the commandline passed
  to the kernel, so the console is fixed to ttyS0/AMA0. Therefore,
  reintroduce an option to choose the console.

- Use a fixed `nr`s for virtconsoles, so that the gdbserver always
  listens on `hvc1`. Ideally, we should use udevs `/dev/virtio-ports/*`
  symlinks, but for some reason these point to `/dev/vportXpY` and not
  to `/dev/hvcY`. TODO: Figure out what the difference is.

- While we're here, remove the duplicated RTC setup which was
  introduced with the virtio-console work a while back.
