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.

-Detect if the platform is vulnerable to the A010022 erratum based on device
-tree properties instead of the SoC family.
