Basically, I would prefer better than "qcom, fw-managed" since this is not
a qcom specific problem.
We already have something like this in mainline where the BAM DMA controller is remotely powered.

As you can see it is already fragmented. Why we need to create one more approach
which is not scalable and specific to SOC vendor?
SCMI or RPMI based firmware is not a QC specific. I also have allergic reaction
when I see drivers modified w/ if (fw_managed) {..} but that is a discussion
for some other day.
For the record, I fully agree with Trilok here.
More importantly, why is the other suggested approach(es) a problem? I
don't get it.
Are we going to do this with each driver on every new board that will be
added?
