This pin functions as a power input pin to the OV5642 camera sensor, but ENET uses it as the h/w workaround for erratum ERR006687, to wake-up the ARM cores on normal RX and TX packet done events. So we need to remove the h/w workaround to support the OV5642. The result is that the CPUidle driver will no longer allow entering the deep idle states on the sabrelite.
