Patch + Kconfig changes to prefer the SOF driver on Intel LPE audio hardware

Hans de Goede requested to merge jwrdegoede/kernel-ark:snd_intel_byt_prefer_sof into os-build

This merge-req implements: https://fedoraproject.org/w/index.php?title=Changes/SofDefaultForIntelLpe

It consists of 4 patches:

  1. A patch making the preferred driver selectable in Kconfig, which is already in -next
  2. Automatic creation of redhat/configs/pending-*/generic/CONFIG_SND_INTEL_BYT_PREFER_SOF files
  3. Move the fedora CONFIG_SND_INTEL_BYT_PREFER_SOF config out of pending and enable it
  4. Add a redhat/rebase-notes.txt with a reminder that on Fedora kernel rebases it should be disabled for F33 and older.

Note I've left the rhel config for this in pending-rhel, leaving the decision of what to do with this up to the RHEL kernel folks. I believe that it makes sense to also enable this for RHEL. Intel LPE audio hardware is used in POS systems which are supported by RHEL and the SST driver will not be maintained anymore going forward, so for RHEL9 it is probably better to switch to the SOF driver which will actually see ongoing maintenance work upstream.
