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: parsers: trx: parse "firmware" MTD partitions only
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Parsing every partition with "compatible" set to "brcm,trx" results in
-parsing both: firmware partition and failsafe partition on devices that
-implement failsafe booting. This affects e.g. Linksys EA9500 which has:
-
-partition@200000 {
-	reg = <0x0200000 0x01d00000>;
-	compatible = "linksys,ns-firmware", "brcm,trx";
-};
-
-partition@1f00000 {
-	reg = <0x01f00000 0x01d00000>;
-	compatible = "linksys,ns-firmware", "brcm,trx";
-};
-
-Check for MTD partition name "firmware" before parsing. Recently added
-ofpart_linksys_ns.c creates "firmware" and "failsafe" depending on
-bootloader setup.
