EXTi (external interrupt) signal can be routed internally as trigger
source for ADC conversions: STM32F4 ADC can use EXTI11.
Retrieve interrupt trigger from DT, so it can be muxed into ADC IP,
via extsel.

STM32 ADC may use EXTi signals routed internally as trigger source
for conversions. Configure them as interrupt to configure this path
in HW to adc.
Note: interrupt handler isn't required here, and corresponding interrupt
can be kept masked at exti controller level.
