      Description
      HSMMCSDBusFreqSet API results into floating point exception error when the input frequency is equal to output frequency.

      Resolution Description
      Added error check to ensure freq_out * 2 is less than freq_in

      Root Cause
      MMCSD Clock(clkd) is calculated as freq_in/(freq_out * 2). Hence clkd is 0 when freq_out * 2 is greater than freq_in leading to floating point exception.
