x86/xen: use capabilities instead of fake cpuid values for mwait

When running as pv domain xen_cpuid() is being used instead of
native_cpuid(). In xen_cpuid() the mwait feature is indicated to be
present or not by special casing the related cpuid leaf.

Instead of delivering fake cpuid values use the cpu capability bit
for mwait instead.
