 [PATCH v2 06/10] ACPI: scan: Do not bind ACPI drivers to fixed event buttons

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

Both ACPI button drivers have been converted to platform ones, so there
is no reason to attempt to bind an ACPI driver to a struct acpi_device
representing a fixed event device button.

Update the relevant code accordingly.

No intentional functional impact.
