[PATCH] ARM: dts: at91: sama5d4_xplained: properly mux phy interrupt

[Alexandre Belloni]

No interrupt were received from the phy because PIOE 1 may not be properly
muxed. It prevented proper link detection, especially since commit
321beec5047a ("net: phy: Use interrupts when available in NOLINK state")
disables polling.
