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.

-MIME-Version: 1.0
-Content-Disposition: inline
-Content-Transfer-Encoding: 8bit
-Content-Type: text/plain; charset="utf-8"
-
-Clean up decode_bits() to use pr_cont(), and move the newline into the
-function rather than at its two callsites. Avoid printing an
-unnecessary space before the newline.
