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: extract code copying NVRAM
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This simplifies function finding NVRAM. It doesn't directly deal with
-NVRAM structure anymore and is a bit smaller.
