PATCH 1/1 arm64: dts: m3ulcb: 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.

Based in a similar patch for the r8a7796 salvator-x by Kazuya Mizuguchi.

Untested due to lack of hardware access.

Thanks, I have queued this up with the typo fixed.
