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: spinand: Add support for XTX XT26G0xA
-
-Add support for XTX Technology XT26G01AXXXXX, XTX26G02AXXXXX and
-XTX26G04AXXXXX SPI NAND.
-
-These are 3V, 1G/2G/4Gbit serial SLC NAND flash devices with on-die ECC
-(8bit strength per 512bytes).
-
-Tested on Teltonika RUTX10 flashed with OpenWrt.
-
-Datasheets available at
-http://www.xtxtech.com/download/?AId=225
-https://datasheet.lcsc.com/szlcsc/2005251034_XTX-XT26G01AWSEGA_C558841.pdf
