[PATCH v1 2/2] ACPI: scan: Adjust white space in acpi_device_add()

["Rafael J. Wysocki" <rjw@rjwysocki.net>]

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

Add empty lines in some places in acpi_device_add() to help
readability and drop leading spaces before the labels in there.

No functional impact.
