ACPI / platform: Use struct acpi_scan_handler for creating devices
Currently, the ACPI namespace scanning code creates platform device objects for ACPI device nodes whose IDs match the contents of the acpi_platform_device_ids[] table. However, this adds a superfluous special case into acpi_bus_device_attach() and makes it more difficult to follow than it has to be. It also will make it more difficult to implement removal code for those platform device objects in the future. For the above reasons, introduce a struct acpi_scan_handler object for creating platform devices and move the code related to that from acpi_bus_device_attach() to the .attach() callback of that object. Also move the acpi_platform_device_ids[] table to acpi_platform.c. Signed-off-by: Rafael J.
