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: add autorescan sysfs
-
-Add the autorescan sysfs in order to enable/disable the DPRC IRQs on
-which automatic rescan of the bus is performed. This is important when
-dynamic creation of objects is needed to happen in a timely manner because
-object creation can be bundled together.
