x86/tsc: Print tsc_khz, when it differs from cpu_khz

If CPU and TSC frequency are the same the printout of the CPU frequency is
valid for the TSC as well:

      tsc: Detected 2900.000 MHz processor

If the TSC frequency is different there is no information in dmesg. Add a
conditional printout:

  tsc: Detected 2904.000 MHz TSC
