ACPI: Attach the ACPI device to the ACPI handle as early as possible

commit eab4b645769fa2f8703f5a3cb0cc4ac090d347af upstream.

Attach the ACPI device to the ACPI handle as early as possible so that OS
can get the corresponding ACPI device by the acpi handle in the course
of getting the power/wakeup/performance flags.
