Changing my device tree overlay to include status="okay" does not seem to be enough to enable me to access that address, whether or not the sound stuff is still around. Note that I am only messing with an overlay. Do I need to change the device tree the board is booted with?
Looking into the source for the davinci-mcasp audio driver that gets loaded by default, there are calls to pm_runtime_get_sync(mcasp->dev) and pm_runtime_put(mcasp->dev), which are probably needed in my code. Next step is to figure out how I am going to get a struct device for the McASP.
