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] staging: fsl_ppfe/eth: support for userspace networking
-
-This patch adds the userspace mode support to fsl_ppfe network driver.
-In the new mode, basic hardware initialization is performed in kernel, while
-the datapath and HIF handling is the responsibility of the userspace.
-
-The new command line parameter is added to initialize the ppfe module
-in userspace mode. By default the module remains in kernelspace networking
-mode.
-To enable userspace mode, use "insmod pfe.ko us=1"
