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] LF-605 mmc: sdhci-of-esdhc: update tuning erratum A-008171
-
-There is an official update for eSDHC tuning erratum A-008171.
-This patch is to implement the changes,
-- Affect all revisions of SoC.
-- Changes for tuning window checking.
-- Hardware hits a new condition that tuning succeeds although
-  the eSDHC might not have tuned properly for type2 SoCs
-  (soc_tuning_erratum_type2[] array in driver). So check
-  tuning window after tuning succeeds.
