Subject: [PATCH v1 4/4] ACPI: PNP: Drop acpi_nonpnp_device_ids[]

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

Now that "system" devices are represented as platform devices, they
are not claimed by the PNP ACPI scan handler any more and platform
devices can be created for ACPI device objects listing "system"
device IDs as their compatible device IDs.

Accordingly, it should not be necessary any more to add device IDs
to acpi_nonpnp_device_ids[], so drop it.

No intentional functional impact.
