ACPI defines _RST method to perform device level reset. After the _RST method is executed, the OS can resume using the device. This patch checks the presence of _RST method and calls the _RST method when reset is requested. Changes from V5: 1. Handle reset function call failures in open and release (new patch). 2. Bring out extra debug information when failure happens (new patch). 3. Address review comments from Eric in ACPI _RST patch.
