The BF537 SIC combines the gpio port H mask A interrupts with the emac rx interrupt, so we need to demux this in software. It also combines the gpio port H mask B and the emac tx interrupts, and the watchdog and port F mask B interrupts, but since we don't support mask B yet, just add the defines for now.
