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: Propagate driver_override for a child DPRC's
- children
-
-When a child DPRC is bound to the vfio_fsl_mc driver via
-driver_override, its own children should not be bound to corresponding
-host kernel drivers, but instead should be bound to the vfio_fsl_mc
-driver as well.
-
-Currently, when a child container is scanned by the vfio_fsl_mc
-driver, child devices found are automatically bound to corresponding
-host kernel drivers (e.g., DPMCP and DPBP objects are bound to the
-fsl_mc_allocator driver, DPNI objects are bound to the ldpaa_eth
-driver, etc), Then, the user has to manually unbind these child
-devices from their drivers, set the driver_override sysfs attribute
-to vfio_fsl_mc driver, for each of them and rebind them.
