x86/tsc: Enumerate BXT tsc_khz via CPUID
Hard code the BXT crystal clock (aka ART - Always Running Timer)
to 19.200 MHz, and use CPUID leaf 0x15 to determine the BXT TSC frequency.
Use tsc_khz to sanity check BXT cpu_khz,
which can be erroneous in some configurations.
(I simplified the original patch from Bin Gao.)
