I have created an issue at gitlab:

   https://gitlab.com/qemu-project/qemu/-/issues/3293

and hopefully this will get fixed in QEMU at some point.

Adding Paolo to the participants, since he presumably knows what to do
with qemu, since he touched that qemu file a couple of months ago.

(The fix looks trivial, as suggested by Alexey: just change the
"uint32_t data[6];" to use target_ulong instead of uint32_t, but
somebody needs to test it and maybe qemu has other rules for register
types)
