The 'stm32vldiscovery' machine ignores the CPU type requested by
the command line. This might confuse users, since the following
will create a machine with a Cortex-M3 CPU:
$ qemu-system-aarch64 -M stm32vldiscovery -cpu neoverse-n1
Set the MachineClass::valid_cpu_types field (introduced in commit
c9cf636d48 "machine: Add a valid_cpu_types property").
Remove the now unused MachineClass::default_cpu_type field.
We now get:
$ qemu-system-aarch64 -M stm32vldiscovery -cpu neoverse-n1
qemu-system-aarch64: Invalid CPU type: neoverse-n1-arm-cpu
The valid types are: cortex-m3-arm-cpu
Since the SoC family can only use Cortex-M3 CPUs, hard-code the
CPU type name at the SoC level, removing the QOM property
entirely.
