Since we already have an 10K pull-down on board, the RXC level on PHY reset will be ~800mV, which is mostly interpreted as 1. On some reboots we get 0 instead and kernel can't detect the PHY properly. Since the default 0x020e07ac value is 0, it is sufficient to remove this entry from the affected imxcfg files. Since we get stable 0 on pin PHYADDR[2], the PHY address is changed from 4 to 0.
