ipa: rkisp1: agc: Simplify predivider calculation
The condition if (std::pow(std::floor(root), 2) < factor) predivider = static_cast<uint8_t>(std::ceil(root)); else predivider = static_cast<uint8_t>(std::floor(root)); can only be false when the factor's root is an integer. In that case, std::ceil(root) and std::floor(root) will be equal. The computation can thus be simplified by always rounding up.
