board: ti: j721e: Update fdt fixup logic for interconnect nodes

The DT nodes on J721E 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.
