* Remove unnecessary patch
- this patch works when compiling and installing manually.
- the dtb with the changes is taken from the kernel and not from u-boot, therefore this patch does not work.
* Add enable-audio-codec-bpim2ultra-kernel.patch
- Add patch to enable audio codec in bpi-m2-ultra with h3 compatible
- Built and tested on Armbian Buster with Kernel 5.11.x (edge)
