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-17580: ASoC: fsl: sai: check for pinctrl status
-
-For some cases (like AMIX) pinctrl may be null - this
-breaks SAI functionality. Enforce pinctrl null pointer
-checking prior calling any function which involves
-pins state changes.
