[PATCH v2 5/5] ACPI: bus: Drop acpi_get_first_physical_node()

["Rafael J. Wysocki" <rafael@kernel.org>]

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

Fold acpi_get_first_physical_node() into acpi_primary_dev_companion()
that is its only remaining caller and drop its signature from the
header file.

No intentional functional impact.
