ravb: Add tx and rx clock internal delays mode of APSR
This patch enables tx and rx clock internal delay modes (TDM and RDM). This is to address a failure 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. With this change APSR internal delay modes are enabled for "rgmii-id", "rgmii-rxid" and "rgmii-txid" phy modes as follows: phy mode | ASPR delay mode -----------+---------------- rgmii-id | TDM and RDM rgmii-rxid | RDM rgmii-txid | TDM Signed-off-by:Kazuya Mizuguchi <kazuya.mizuguchi.ks@renesas.com> Signed-off-by:
