This adds logic for taking SDM_DIN (Sigma Delta Modulator) setting into
the equation to calculate the effective N value for PLL which supports
fractional divider.

The effective N = NDIV + 1/2 + SDM_DIN/2^13, where NDIV is the integer
feedback divider.

Thanks for making the suggested changes.

v5:
  - made use of sdm_en_mask when possible to clean up logic
  - added kerneldoc info for new struct params
  - Added info about SDM near sdm_set_data
  - rewrote check in sdm_set_data to make it clearer
