"cpuid-0xb" was previously disabled only on PC-Q35-2.6 and
PC-I440FX-2.6 machines, but PC v2.6 machines have been deprecated and
will be removed.
Considerring it may have external use, so deprecate it before removal.

+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The ``cpuid-0xb`` is used to control whether to encode CPUID 0xB leaf or not.
+Only legacy x86 CPUs didn't have 0xB leaf, and the ```level``` property can
+control whether CPUID exposes the 0xB leaf and emulate legacy CPUs. This
+property was previously set to false only on PC-Q35-2.6 and PC-I440FX-2.6
+machines, but PC v2.6 machines have been removed. Deprecate this property to
