Fixed rt5651 sound output on OrangePi 4

AR-205

Based on the research of iamdrq in the Armbian forums.

Tested with dev and current.

Why did you remove patches from the Arabian build system?

I did not remove any patches ;-)
I simply deleted the branch that was already merged into master.

OK, thanks, now I understand.

Bluetooth doesn't work.
This hack: https://forum.armbian.com/topic/13601-orange-pi-4-kernel-5xx-rt5651-sound-and-bluetooth-fixed/?tab=comments#comment-98961
helped me again. Bluetooth now work, the sound is there through it.
But now there is no sound from the 3.5 Jack. I didn't find how to fix it. I don't want to roll back to the old kernel from that post:
