Guru Das Srinagesh a6733474ba clk: pwm: Use 64-bit division function ...

Since the PWM framework is switching struct pwm_args.period's datatype
to u64, prepare for this transition by using div64_u64() to handle a
64-bit divisor.

Also ensure that divide-by-zero (with fixed_rate as denominator) does
not happen with an explicit check with probe failure as a consequence.
