loader: enable dynamic interrupt connection on Arduino Uno Q

[mirinae3145]

Tested with timer interrupts

void TIM3_IRQHandler(const void*) {
  if (TIM3->SR & TIM_SR_CC2IF) {
    TIM3->SR = 0;
    (void)TIM3->SR;
  }
}

irq_connect_dynamic(TIM3_IRQn, 0, TIM3_IRQHandler, nullptr, 0);
irq_enable(TIM3_IRQn);

Looks like a good addition, I assume it will or does also work on other boards like GIGA and Portenta H7?

It also partially solves some of the stuff I was looking at with issue: #388

For example if I wish to write my own DCMI driver outside of the Device Tree, How would I address all of the IO pins.
Luckily looks like the pins on JMISC are given pin numbers on the Q. But not the case with the Portenta H7.

Again looks good.

@KurtE Glad to hear it helps, but sorry that I don't know about other boards.
@pillo79 Thanks for the approval. What remains to be merged?
