[PATCH] tests/qtest: Do not use versioned pc-q35-5.2 machine anymore

[Stefan Hajnoczi]

As of QEMU v11.1.0, the v5.2.0 machines are not usable anymore.

Use the latest x86 q35 machine instead, otherwise we get:

  $ qemu-system-x86_64 -M pc-q35-5.2
  qemu-system-x86_64: unsupported machine type: "pc-q35-5.2"
  Use -machine help to list supported machines

See commit a35f8577a07 ("include/hw: add macros for deprecation
& removal of versioned machines") and f59ee044067 ("include/hw/boards:
cope with dev/rc versions in deprecation checks") for explanation
on automatically removed versioned machines.

This commit message is taken from commit 9eef3854d309 ("tests/qtest: Do
not use versioned pc-q35-5.0 machine anymore") by Philippe Mathieu-Daudé
<philmd@linaro.org>.

I wonder whether we should rather remove the test completely instead? Those 
tests based on the fuzzers rely on a certain way of doing their MMIO - if a 
newer machine type has a slightly different MMIO layout, the test basically 
does not test anything useful anymore. WDYT?
