smiapp_pll_calculate() function. Make them const.

Sakari Ailus f5984bbdf4 [media] smiapp-pll: Parallel bus support
Support sensors with parallel interface.
Make smiapp_pll.flags also 8-bit so it fits nicely into two 32-bit words
with the other 8-bit fields.

Sakari Ailus 6de1b143a4 [media] smiapp-pll: Try other pre-pll divisors
The smiapp pll calculator assumed that the minimum pre-pll divisor was

Typically there are just a few alternatives.
