[PATCH v5 04/51] x86/tsc: Restrict recalibrate_cpu_khz() export to p4-clockmod and powernow-k7

[Sean Christopherson]

Export recalibrate_cpu_khz() only for its two users, p4-clockmod.ko and
powernow-k7.ko, to help document that recalibration is relevant only to
ancient CPUs.

For all intents and purposes, no functional change intended.
