ARM: dts: imx6dl-yapp4: Use rgmii-id phy mode on the cpu port
Use rgmii-id phy mode for the CPU port (MAC0) of the QCA8334 switch to add delays to both Tx and Rx clock. It worked with the rgmii mode before because the qca8k driver (incorrectly) enabled delays in that mode and rgmii-id was not implemented at all. Commit 5ecdd77c61c8 ("net: dsa: qca8k: disable delay for RGMII mode") removed the delays from the RGMII mode and hence broke the networking. To fix the problem, commit a968b5e9d587 ("net: dsa: qca8k: Enable delay for RGMII_ID mode") was introduced. Now the correct phy mode is available so use it.
