[SRU Justification]
[Impact]
Some Dell laptops's audio amplifier does not work as expected and need the
external amplifier instead of default one of Realtek RT722 codec.

("8457ad05bbc48355068bbc7d4cef242affbe0f63")
[Test Case]
1. Boot up the Dell laptops with the SKU ID: 0DD3 or 0DD4

accordingly.
[Where problems could occur]
Only applied for particular Dell SKU. No regression expected at the current
