kernel: Add device tree for p3041ds for USDPAAdizzy

A new device tree for USDPAA support has been added for p3041ds 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.
