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] imx busfreq: Add API header file
-
-Add sufficient enough definitions so that drivers which call
-request_bus_freq and release_bus_freq can compile even if
-CONFIG_HAVE_IMX_BUSFREQ is missing.
