[DRIVERS] net: phy: dp83867: rework delay rgmii delay handling

Based on this commit: https://git.seco.com/edgehog/bsp/nxp/u-boot-seco-imx/-/commit/20f7ea4c35ff98003c29eec442700af04496b49f

Based on commit c11669a2757e ("net: phy: dp83867: Rework delay rgmii delay handling") of mainline linux kernel.

The current code is assuming the reset default of the delay control register was to have delay disabled. This is what the datasheet shows as the register's initial value. However, that's not actually true: the default is controlled by the PHY's pin strapping.

This patch:

  • insures the other direction's delay is disabled If the interface mode is selected as RX or TX delay only
  • validates the delay values and fail if they are not in range
  • checks if the board is strapped to have a delay and is configured to use "rgmii" mode and warning is generated that "rgmii-id" should have been used.
