board: ti: am65x: Update fdt fixup logic for interconnect nodes

Browse Source 
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.
