[PATCH 09/11] ACPI: remove ACPI dependency on PM

[Bjorn Helgaas <bjorn.helgaas@hp.com>]

Allow ACPI to build without CONFIG_PM.

CONFIG_PM (power management) gives us things like suspend/resume
support.  The device discovery and configuration functionality of
ACPI is still useful even without power management.
