Subject: [PATCH] UBUNTU: ACPI: Attach the ACPI device to the ACPI handle as early as possible

Bug: 69925
upstream commit eab4b64

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

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.
