media: ccs-pll: Start OP pre-PLL multiplier search from correct value

commit 660e613d05e449766784c549faf5927ffaf281f1 upstream.

The ccs_pll_calculate() function does a search over possible PLL
configurations to find the "best" one. If the sensor does not support odd
pre-PLL divisors and the minimum value (with constraints) isn't 1, other
odd values could be errorneously searched (and selected) for the pre-PLL
divisor. Fix this.
