Subject: [PATCH] pmdomain: core: Print a message when unused power domains
 are disabled

In a similar spirit to commit 12ca59b91d04 ("clk: Print an info line
before disabling unused clocks"), print the message in both ignore AND
cleanup cases to better inform the user (and more importantly, the
developer) when it happens.
