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] firmware: bcm47xx_nvram: rename finding function and its
- variables
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-1. Use "bcm47xx_" function name prefix for consistency
-2. It takes flash start as argument so s/iobase/flash_start/
-3. "off" was used for finding flash end so just call it "flash_size"
