The "ti,hwmods" should be in the parent node now. But you may not even need
it, see the reset comment I made for the parent node patch.

And then you should be able to also leave out status = "disabled" as the
hardware is there for sure and we can idle it. Then a board specific
dts file can set it to "disabled" if reallly needed. Setting everything
manually to "disabled" and then again to "enabled" is the wrong way
around, the default is "enabled".
