Either this property or the unit address is wrong as they do not match.
The bindings currently mandates that vendor property you added
("qcom,adsp-pil-mode), but you left it out here.

clock before reset for some sort order.

Your preliminary version of this patch also added a reset to swr0, which
has been left out here. Was that not needed?

Your driver (and the binding example) seems to suggest that the size
here should be 0x12000.
The vendor property appears to be missing here too (or the binding is
incorrect).
