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: bcm_sf2: refactor LED regs access
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-1. Define more regs. Some switches (e.g. BCM4908) have up to 6 regs.
-2. Add helper for handling non-lineral port <-> reg mappings.
-3. Add support for 12 B LED reg blocks on BCM4908 (different layout)
-
-Complete support for LEDs setup will be implemented once Linux receives
-a proper design & implementation for "hardware" LEDs.
