soc: mellanox: Don't register for counter wrap interrupts

By default the TRIO_MAP_EVT_CTR counts incoming packets. It's a
32 bit counter and when it wraps we get a TRIO_MAP_EVT_CTR_INT
interrupt which is reported to the console as a warning. That's
confusing, so don't have the mlx-trio driver register for that
event. If it's useful, then it can be handled by the mlx-pmc
driver instead.

Also, check for a num_irqs property instead of hard-coding that
number in the driver. That way we can change the number of
events in the future without breaking backward compatibility
with UEFI.
