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] modpost: add a helper to get data pointed by a symbol
-
-When CONFIG_MODULE_REL_CRCS is enabled, the value of __crc_* is not
-an absolute value, but the address to the CRC data embedded in the
-.rodata section.
-
-Getting the data pointed by the symbol value is somewhat complex.
-Split it out into a new helper, sym_get_data().
-
-I will reuse it to refactor namespace_from_kstrtabns() in the next
-commit.
