kernel: delete Linux 5.4 config and patches

As the upcoming release will be based on Linux 5.10 only, remove all
kernel configuration as well as patches for Linux 5.4.
There were no targets still actively using Linux 5.4.

-Subject: [PATCH] MLK-15330-3 dma: fsl-edma-v3: add dual fifo support
-
-There is Audio dual fifo cause that fill fifo one by one and
-loop back after every minor loop:
-  -- fill the first 32bit width fifo
-  -- fill the next 32bit width fifo
-  -- +MLOFF signed offset after the above two FIFOs filled
-  -- loop back to the first step to handle the next minor loop.
