linux-5.12-legion-sound-0.0.9.patch - Improved 13s Gen 2 support

Big thanks for Vince Morel for providing cleaned up verbs for initialization on the 13s Gen2. We're down from around 400 to just 14!

13s Gen2 users, please test. Please ensure that audio still works after unplugging headphones and report on quality as well. When comparing audio quality, please disable any advanced audio features (such as Dolby) under Vantage as such features are unlikely to be supported under Linux anyway (Dolby is unsupported for example).

Now for some bad news. Between my job and family, I really don't have time to keep trying to figure out how to get this work into the kernel especially when I don't even get any responses back at all. Probably tonight, I'll re-share this patch as a patchset of 3 in case anyone else wants to give it a shot, but I really just don't have the time anymore.

And for good news, I'll likely have a 2021 Lenovo Legion at some point in August (the order has been placed since early July, but who knows when I'll actually receive it due to all the supply issues). Once I have that, I'll do this one more time and try to get sound working there as well.

Once I can start the process with the 2021 Legion, I'll finish up the documentation work that I have in the pipeline. I'll document the process as I go through it again to make sure all is complete.
