dts updates for ti81xx for v5.1 merge window

Two changes to add support for McGill University's IceBoard telescope
ARM + FPGA instrumentation board. This board is used for several
telescopes around the world, see the related device tree commit for
some interesting links for more information.

Note that these changes are based on the related ti81xx soc changes.
