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: add removed helper syscon_regmap_lookup_by_pdevname
-
-The helper syscon_regmap_lookup_by_pdevname has been removed in 29d14b668d2f
-("mfd: Remove unused helper syscon_regmap_lookup_by_pdevname") due to lack
-of users.
-
-Thus, we have to maintain it locally.
-
-This patch includes a fix due to changes in driver_find_device;
-kernel commit: 92ce7e83b4e5 ("driver_find_device: Unify the match function
-with class_find_device()")
