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] net: dsa: felix: Fix probing allocation and cleanup path
-
-dsa_switch_alloc() uses managed (devm_alloc) allocation
-to alloc 'ds'.  kfree()-ing 'ds' results in memory corruption.
-kfree(ds) seems harmless on the error path, however for this
-particular device, dsa_register_swtich() deffers probing to
-allow the enetc driver to probe the master port first.
-This results in kfree(ds) being called during the first
-probing attempt of felix, followed by a NULL poiter access
-crash during enetc driver probing (when accessing its net_device).
-
-This patch fixes following crash (triggerred in the enetc driver by
-the probing routine of the felix driver):

-As a result of the fix, struct felix allocation also needs to
-be converted to managed allocation (devm_alloc).
