[PATCH v1] ACPI: PM: Adjust messages regarding postponed ACPI PM

[PATCH v1] ACPI: PM: Adjust messages regarding postponed ACPI PM

[Rafael J. Wysocki]

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

The debug messages added by commit f7599be2bb76 ("ACPI: PM: postpone
bringing devices to D0 unless we need them") in acpi_subsys_resume_early()
and acpi_subsys_resume() are not quite accurate because what is postponed
is not just a transition to D0, but also an adjustment of the device's
wakeup setting (which may involve disabling a GPE among other things).
Moreover, these messages don't even mention ACPI.

Rephrase them and adjust the style to match other messages in device_pm.c.

Makes sense to me.
