sm_enable_interrupt uses this function, but if I have a PIO program that wants to wait for the interrupt, I need to re-write the function as below:

fn get_irq_regs(irq: Irq) *volatile Irq.Regs {
    const PIO0 = microzig.chip.peripherals.PIO0;
    const irq_regs = @as(*volatile [2]Irq.Regs, @ptrCast(&PIO0.IRQ0_INTE));
    return &irq_regs[@intFromEnum(irq)];
}

And this is hardcoded for PIO0. I can't even call get_regs because that method is also not public.
