ARM: SoC DT fixes for v5.8

These are the latest device tree fixes for Arm SoCs:

  - TI Keystone2 ethernet regressed after a driver change broke with
    incorrect phy-mode in a board's DT source.

  - A similar fix is needed for two i.MX boards that were missed in
    an earlier bugfix.

  - DT change for Armada 38x allowing to add the register needed to fix
    NETA lockup when repeatedly switching speed.

  - One fix on imx6qdl-icore pin muxing to get USB OTG_ID and SD card
    detect work correctly.

  - Two fixes for the Allwinner SoCs, one to relax the CMA allocation
    ranges that were failing on older SoCs and one to fix Cedrus on the H6.
