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] bus: fsl-mc: Some apis are made public for vfio
-
-Some of the APIs and data-structures are required for VFIO.
-This patch moves dprc.h to public header files.
-Also some APIs of mc-bus are made public for vfio.
