iio: adc: qcom-spmi-adc5-gen3: Update ratios for SMB_* channels for ADC7

Browse Source 
As per the hardware recommendation, add a ratio of 41/40 (i.e.
numerator 40 and denominator 41 based on how it's used in our
calculations) for the ADC channels that use SMB_TEMP pin because
of the voltage divider circuit with a 1 K and 40 K in parallel.
