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-15330-1: dma: fsl-edma-v3: combine two cells into one
-
-For dual fifo case, fsl-edma-v3 need add another cell. It's not friendly
-for user and it's possible other cells maybe added to other use cases,
-so combine two cells into one now, and for some special use cases such as
-dual fifo property can directly be passed by one bit of cell3 rather than
-another cell.
