Subject: [PATCH] syscore: Use pm_pr_dbg() for syscore_{suspend,resume}()

The debug messages about what syscore suspend/resume hooks are called
are only present if you have initcall debugging enabled. Let's move
these messages to pm_pr_dbg() so that the syscore PM messages are
included along with all the other PM debugging info that can be seen
during suspend/resume debugging.
