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 device binding path 'driver_override'
-
-This patch is required for vfio-fsl-mc meta driver to successfully bind
-layerscape container devices for device passthrough. This patch adds
-a mechanism to allow a layerscape device to specify a driver rather than
-a layerscape driver provide a device match.
-
-This patch is based on following proposed patches for PCI and platform
-devices
-- https://lkml.org/lkml/2014/4/8/571  :- For Platform devices
-- http://lists-archives.com/linux-kernel/28030441-pci-introduce-new-device-binding-path-using-pci_dev-driver_override.html
-:- For PCI devices
-
-Example to allow a device (dprc.1) to specifically bind
-with driver (vfio-fsl-mc):-
- - echo vfio-fsl-mc > /sys/bus/fsl-mc/devices/dprc.1/driver_override
- - echo dprc.1 > /sys/bus/fsl-mc/drivers/fsl_mc_dprc/unbind
- - echo dprc.1 > /sys/bus/fsl-mc/drivers/vfio-fsl-mc/bind
