From: Sourab Gupta <sourab.gupta@intel.com>

Exporting clocks_calc_mult_shift is helpful for drivers to calculate
the mult/shift values for their clocks, given their frequency.
This is particularly useful when such drivers may want to associate
timecounter/cyclecounter abstraction for their clock sources, in order
to use the cross timestamp infrastructure for syncing device time with
system time.
