Enable nodes required for q6 remoteproc bring up.

I just recently became aware of this series, and have some questions...

This file does not currently exist in linux-firmware.
Instead there is q6_fw.mdt with associated .b* files.

How do we transition from .mdt to .mbn given that distros update their version
of linux-firmware independently from kernel updates? Will we need to have both
the .mdt and .mbn files present for some period of time? Are there associated
changes which no longer attempt to load the .mdt files?

Since there are no in-kernel users for this one (the ipq8074 WCSS driver
requests that but no DT is wired up), I would say we should promptly move to
MBN..

I ask because I've been told the ath11k/ath12k drivers will also need to
transition their firmware loading from m3_fw.mdt to m3_fw.mbn, and I'm not
sure how to make that transition.

I can't see any m3_fw.mdt in the tree or l-f, unless the m3.bin qualifies
