This adds "syscon" to the compatible properties for the eth0/eth1 nodes in ar7100.dtsi. Without this, a kernel panic is encountered on boot with some ar7100 boards. This for some reason wasn't an issue for the WNDR3800, which uses a Realtek switch chipset, but the panic was encountered on the RouterStation Pro (using an AR8216 switch) and some other boards that haven't yet been merged. The panic message mentions an unaligned access and happens in ag71xx_mdio_probe in drivers/net/ethernet/atheros/ag71xx/ag71xx_mdio.c. Even if the unaligned access is fixed, the ag71xx_mdio probe still fails without the "syscon" property. This was already being worked around in ar7161_ubnt_routerstation-pro.dts by overriding the compatible property, so this commit removes that as well. All of the other ath79 .dtsi already have this property, so no changes are needed elsewhere. Signed-off-by: Matt Merhar <mattmerhar@protonmail.com>
