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] LFV-26 crypto: caam - fix Secure Memory driver init
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-SM driver is buggy, since it runs irrespective of the presence of
-the caam-sm DT node.
-This causes issues on SoCs that have caam HW, but without support
-for secure memory.
-
-Let's transform the module in a library, in the same way (and for
-the same reasons) we did for the other job ring-dependent drivers
-(caamalg, caamhash etc.) in
-commit 1b46c90c8e00 ("crypto: caam - convert top level drivers to libraries")
-
-SM test module is also updated, to run only when needed.
-
-Fixes: 54e3fcf89f97 ("MLKU-25-3 crypto: caam - add Secure Memory support")
