Earlier attempt to move am335x mcasp to probe with ti-sysc
interconnect target module caused audio to stop working and and
the dts changes were reverted by commit 5d2632a577ba ("ARM: dts:
Revert am335x mcasp ti-sysc changes").
Turns out we were missing the l3 data port ranges for mcasp. This
caused mcasp dma to attempt to use wrong port address. So let's
try again essentially reverting the earlier revert and adding the
missing l3 data port ranges.

Peter, can you please test with your bbb + audio cape?
