lenovo/legion/16irx8h: fix audio and remove invalid kernel params
- Remove snd_hda_intel.patch parameter (firmware files don't exist) - Remove bluetooth.enable_iso=1 (not supported in kernel 6.16) - Add detailed comments explaining TAS2781 CRC workaround - Clarify that model=legion-y7000 is temporary until kernel quirk lands - Enable redistributable firmware for audio support Tested working: Audio, Bluetooth, TAS2781 codec binding
