There is no need to generate the CSR XML if the Zicsr extension

Should we generate the FPU XML or Vector XML when Zicsr is not enabled?
Good point. I think we should disable that too.
Seems reasonable. Did you want to do that as part of a v3, or just as a
follow-on fix?
I looked at this further.
The FPU / Vector XML is guarded by the " env->misa_ext" check. If
Zicsr is disabled while F or V extension is off, QEMU will error out
in riscv_cpu_realize() earlier before the gdbstub init.
