The DT nodes on AM65x SoCs currently use a node name "interconnect" for the various interconnects. This name is not following the DT schema, and should simply be "bus". Update the fdt fixup logic to use both the current and the expected corrected path names so that this logic won't be broken with newer kernels. The logic also corrects the crypto node name as the DT node unit-addresses are all expected to be lower case.
