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.
