[PATCH v2 2/5] ACPI: scan: Relocate acpi_bus_trim_one()

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

Relocate acpi_bus_trim_one() (without modifications) so as to avoid the
need to add a forward declaration of it in a subsequent patch.

No functional changes.

v1 -> v2: Add R-by from Jonathan.
