Devi Priya f7b7d30158 clk: qcom: clk-rcg2: Fix clock rate overflow for high parent frequencies 
If the parent clock rate is greater than unsigned long max/2 then
integer overflow happens when calculating the clock rate on 32-bit systems.
As RCG2 uses half integer dividers, the clock rate is first being
multiplied by 2 which will overflow the unsigned long max value.
Hence, replace the common pattern of doing 64-bit multiplication
and then a do_div() call with simpler mult_frac call.

Fixes: bcd61c0f535a ("clk: qcom: Add support for root clock generators (RCGs)")
