Thus, these GPIOs are requested at probe time without considering if there are other peripherals that need them. The Ethernet IRQ GPIOs are shared with SDHI2. Selection between Ethernet and SDHI2 is done through a hardware switch. To avoid scenarios where one wants to boot with SDHI2 support and some SDHI pins are not propertly configured because of the GPIO hogs, guard the Ethernet IRQ GPIO hogs with the proper build flag.
