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 495/497] mtd: core: add get_mtd_device_by_node
-
-Add function to retrieve a mtd device by its OF node. Since drivers can
-assign arbitrary names to mtd devices in the absence of a label
-property, there is no other reliable way to retrieve a mtd device for a
-given OF node.
