[PATCH v1 3/6] x86/tsc: Add missed header to tsc_msr.c

[Andy Shevchenko]

Add a missed header otherwise compiler warns about missed prototype:

CC      arch/x86/kernel/tsc_msr.o
arch/x86/kernel/tsc_msr.c:73:15: warning: no previous prototype for âcpu_khz_from_msrâ [-Wmissing-prototypes]
   unsigned long cpu_khz_from_msr(void)
                 ^~~~~~~~~~~~~~~~
