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] fsl/fman: backup and restore ICID registers
-
-During probing, FMAN is reset thus losing all its register
-settings. Backup port ICID registers before reset and restore
-them after, similarly to how it's done on powerpc / PAMU based
-platforms.
-This also has the side effect of disabling the old code path
-(liodn backup/restore handling) that obviously make no sense
-in the context of SMMU on ARMs.
