hvf_get_supported_cpuid() is only defined for x86 targets
(in target/i386/hvf/x86_cpuid.c).
Its declaration is pointless on all other targets.

All the calls to it in target/i386/cpu.c are guarded by
a call on hvf_enabled(), so are elided when HVF is not
built in. Therefore we can remove the unnecessary function
stub.
