OMAPDSS: DSS: add new clock calculation code
Add new way to iterate over DSS clock divisors. dss_div_calc() provides
a generic way to go over all the divisors, within given clock range.
dss_div_calc() will call a callback function for each divider set,
making the function reusable for all use cases.
