It can be discussed how useful a print is after a successful probe. In the
SCMI power domain case it's seems valuable, as it let us inform about the
number of initialized power domains too, which is fetched from firmware.

Therefore, let's add a print about this, which also aligns with the
behaviour of the SCMI perf domain driver.

I always assumed it was already there as dev_debug() but I am wrong.

Hi,

yes indeed we tend to print such 'summary' info at the end of a
successful probe in other SCMI drivers.

LGTM.

Thanks! I have queued this up for v7.1.

Kind regards
