Yeah, I'm pretty sure it didn't work.  I've managed to find a system
which instantiates the IP so hopefully I can modify it to trigger the
issue and test directly rather than working blind, I've also noticed
that we're getting

[   15.430306] cadence-qspi 13010000.spi: Runtime PM usage count underflow!

even in normal operation (on that system anyway) so the runtime PM
handling is definitely unhappy.
