Subject: [PATCH 012/286] arm64: dts: r8a7796: salvator-x: Fix EthernetAVB PHY
timing
Set PHY rxc-skew-ps to 1500 and all other values to their default values.
This is intended to to address failures in the case of 1Gbps communication
using the by salvator-x board with the KSZ9031RNX phy. This has been
reported to occur with both the r8a7795 (H3) and r8a7796 (M3-W) SoCs.
