Change subject: x86/tsc: Only call tsc_freq_mhz once to init clock
......................................................................

Patch Set 1:

tsc_freq_mhz() function can only return 0 in below cases

1. CPUID 15h not supported
2. CPUID 16h not supported
3. CPUID 15h is returning 0 in core_crystal_nominal_freq_khz

if that would have the case then why its only happening 2nd cold boot and not always ?
