kernel: Add device tree for p2041rdb for USDPAA
A new device tree for USDPAA support has been added for p2041rdb platform. This was necessary to allow the usage of an ethernet interface as a normal one, that interfaces with the Linux kernel network stack. In the beginning all the interfaces were allocated to USDPAA, so they were not visible to the Linux kernel. For the development process this would mean the impossibility to boot using a nfs or to connect via ssh.
