Subject: [PATCH] ACPI: power: Use dev_dbg() to print some messages

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

The messages printed by acpi_resume_power_resources() and
acpi_turn_off_unused_power_resources() are not important enough to be
printed with pr_info(), so use dev_dbg() instead of it to get rid of
some noise in the kernel log.
