Is there some situation when we would want to say we're booting from DT
when we aren't? Just wondering about the quotes.

You shouldn't need to set this explicitly, the generic code should be
able to pick a number for you - if you do need this number please
explain why the number was chosen in the comments (or fix the core to
guess better). At the minute the core just makes up a number too but at
least then it's a consistent random number between platforms.
Can you also get away without the pcm_hardware - the core should also
have support for discovering this by querying the DMA controller?
