[PATCH 0/2 v2] x86/tsc: Update tsc crystal_khz whitelist

[Prarit Bhargava]

native_calibrate_tsc() contains a whitelist of models that have a known
TSC frequency that differs from the CPU frequency.  This patchset
switches the code from using magic numbers to using the defines in
asm/intel-family.h and adds new processors to the whitelist.

v2: peterz, fixed typo in patch 0002.  There was some question if the value
was supposed to be 25000 or 24000.  Experimenting on an 0x55 processor shows
that 25000 is correct.
