kernel: add device tree for t4240rdb
A device tree (dts) is added for USDPAA support on t4240rdb. In the default USDPAA dts, all the ethernet interfaces are dedicated to USDPAA, so that they are not visible to Linux kernel. This brings difficulty for development, such as nfs booting and ssh login. In the new dts, one ethernet interface is reserved for Linux kernel network stack, and the others are for USDPAA.
