[RFC PATCH v2 7/7] kvmclock: Unexport kvmclock clocksource

[Peter Hilber]

The KVM PTP driver now refers to the clocksource id CSID_X86_KVM_CLK, so
does not need to refer to the clocksource itself any more. There are no
remaining users of the clocksource export.

Therefore, make the clocksource static again.
