[PATCH 1/2] imx: kontron-sl-mx8mm: Sync dts files and fix ethernet

[Frieder Schrempf]

From: Frieder Schrempf <frieder.schrempf at kontron.de>

This syncs the devicetree files with the latest Linux kernel (5.19-rc2).
This also fixes the currently broken ethernet support:

Before:

  Net:   Could not get PHY for FEC0: addr 0

After:

  Net:   eth0: ethernet at 30be0000
