[PATCH v3 39/41] x86/paravirt: Move using_native_sched_clock() stub into timer.h

[Sean Christopherson <seanjc@xxxxxxxxxx>]

Now that timer.h ended up with CONFIG_PARAVIRT #ifdeffery anyways, move the
PARAVIRT=n using_native_sched_clock() stub into timer.h as a "free"
optimization.

No functional change intended.
