Merge the tsc calibration code for the 32bit and 64bit kernel.
The paravirtualized calculate_cpu_khz for 64bit now points to the correct
tsc_calibrate code as in 32bit.
Original native_calculate_cpu_khz for 64 bit is now called as calibrate_cpu.
Also moved the recalibrate_cpu_khz function in the common file.
Note that this function is called only from powernow K7 cpu freq driver.

Move the basic global variable definitions and sched_clock handling in the
common "tsc.c" file.
- Unify notsc kernel command line handling for 32 bit and 64bit.
- Functional changes for 64bit.
- "tsc_disabled" is updated if "notsc" is passed at boottime.
- Fallback to jiffies for sched_clock, incase notsc is passed on
commandline.
