x86/tsc: Make recalibrate_cpu_khz() export GPL only

bp3tk0v · bp3tk0v · commit 8fe6d8494758 · 2023-02-11T10:44:07.000+01:00
A quick search doesn't reveal any use outside of the kernel - which would be questionable to begin with anyway - so make the export GPL only. Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de> Link: https://lore.kernel.org/r/Y599miBzWRAuOwhg@zn.tnic
