JFTR all randconfig means is that it doesn't seem like a configuration a
human is likely to generate for use on an actual system as opposed to
build coverage - in this case the driver is for the PMIC for some new
ARM SoCs so it's unlikely that someone would want to run the driver on a
system that doesn't have DT (and hence IRQ domains) enabled.

With this sort of dependency error failures are generally either in
configurations you'd expect people to want to run (which obviously
affect users), in allXconfig builds (which get run a lot for all sorts
of reasons and so are urgent even if it's unlikely people will use them
in production) or in randconfig builds (which should work and are
potentially sensible configurations but can also turn up combinations
that aren't that realistic).  All of these should be fixed if they
break.
