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] mtd: spi-nor: fix 4-byte opcode support for w25q256
-Date: Wed, 15 Apr 2020 16:48:30 +0300
-Message-ID: <1586958510-24012-1-git-send-email-mantas@8devices.com>
-
-There are 2 different chips (w25q256fv and w25q256jv) that share
-the same JEDEC ID. Only w25q256jv fully supports 4-byte opcodes.
-Use SFDP header version to differentiate between them.
-
-for OpenWRT only: rebased to linux-v5.4
