This patch allows boards to select a max ADC clock speed. This could be handy if the board wants to clock the ADC differently according to the board's front end analog circuitry or MCU model's ADC capabilities.
This patch ensures that the ADC's max clock speed is not exceded.
This patch increases the board's ADC clock speed to the MCU's maximum speed.

Contribution description
This patch allows boards to declare their max ADC clock speed. As an example, the nucleo-f767zi declares it's ADC clock speed to be 36MHz (the max speed of the board's MCU).
Testing procedure
The change is minor and fairly safe. I verified that the macro works by declaring it to "foo" in
periph_conf.hto trigger a compiler error. Beyond that, it is up to board maintainers to use the macro wisely.Issues/PRs references
