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] staging: fsl_ppfe/eth: handle ls1012a errata_a010897
-
-On LS1012A rev 1.0, Jumbo frames are not supported as it causes
-the PFE controller to hang. A reset of the entire chip is required
-to resume normal operation.
-
-To handle this errata, frames with length > 1900 are truncated for
-rev 1.0 of LS1012A.
