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: rawnand: brcmnand: improve hamming oob layout
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit

-The current code generates 8 oob sections:
-S1	1-5
-ECC	6-8
-S2	9-15
-S3	16-21
-ECC	22-24
-S4	25-31
-S5	32-37
-ECC	38-40
-S6	41-47
-S7	48-53
-ECC	54-56
-S8	57-63
-
-Change it by merging continuous sections:
-S1	1-5
-ECC	6-8
-S2	9-21
-ECC	22-24
-S3	25-37
-ECC	38-40
-S4	41-53
-ECC	54-56
-S5	57-63
