Simon Horman 8703ba77ec arm64: dts: renesas: ebisu, draak: Limit EtherAVB to 100Mbps
* According to the R-Car Gen3 Hardware Manual Errata for Rev 1.00 of
  August 24, 2018, the TX clock internal delay mode isn't supported
  on R-Car E3 (r8a77990) and D3 (r8a77995).

* TX clock internal delay mode is required for reliable 1Gbps communication
  using the KSZ9031RNX phy present on the Ebisu and Draak boards.

Thus, the E3 based Ebisu and D3 based Draak boards can not reliably
use 1Gbps and the speed should be limited to 100Mbps.

Based on work by Kazuya Mizuguchi.
