nit: since this is now a singleton patch in v5 (because patches #1 -
#7 landed), the general policy is to drop the "8/8" in the subject.
AKA I believe the subject of the patch ought to have been:

[PATCH v5] arm64: dts: qcom: sdm845: Add Q6V5 MSS node

It would be handy if you added a label here, AKA:

mss_pil: remoteproc@4080000 {

It's expected that boards will need to refer to this node so that they
can provide a firmware-name, so you need to give them a label to grab
onto.

...and actually, I wonder if boards will also need to be able to set
status = "okay"? Right now they don't because you don't have a status
= "disabled" in sdm845.dtsi, but maybe you should? Are there ever
going to be any boards with sdm845 that don't hook up the modem?
