Rand Deeb 5fe7bdbe4f ssb: Fix division by zero issue in ssb_calc_clock_rate 
[ Upstream commit e0b5127fa134fe0284d58877b6b3133939c8b3ce ]

In ssb_calc_clock_rate(), there is a potential issue where the value of
m1 could be zero due to initialization using clkfactor_f6_resolv(). This
situation raised concerns about the possibility of a division by zero
error.

We fixed it by following the suggestions provided by Larry Finger
<Larry.Finger@lwfinger.net> and Michael Büsch <m@bues.ch>. The fix
involves returning a value of 1 instead of 0 in clkfactor_f6_resolv().
This modification ensures the proper functioning of the code and
eliminates the risk of division by zero errors.
