stm32/ADC: Fix prescaler calculation to include max frequency.
Due to the integer rounding rules one has to subtract 1 from the numerator.
For example:
Let max clock be 55 and supplied clock be 110
110/55 = 2 which results in the divider being set to 4 and the clock after division ends up being 27 instead of 55
Subtracting 1 to the numerator get around the rounding issue
109/55 = 1 which results in the divider being set to 2 and the clock after division ends up being 55 which is exactly max clock
