[PATCH v5 3/7] x86/cpu: Make X86_FEATURE_LFENCE_RDTSC a scattered feature bit

[Kim Phillips]

It's a part of the CPUID 0x80000021 leaf, and will be grouped
with other feature bits to being propagated via kvm_set_cpu_caps()
instead of open-coding them in __do_cpuid_func().

Unlike the other CPUID 0x80000021 EAX feature bits,
X86_FEATURE_LFENCE_RDTSC already had an entry in cpufeatures.h.
