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] vfio/fsl-mc: Scan DPRC objects on vfio-fsl-mc driver bind
-
-The DPRC(Data Path Resource Container) device is a bus device and has
-child devices attached to it. When the vfio-fsl-mc driver is probed
-the DPRC is scanned and the child devices discovered and initialized.
