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.
