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] can: flexcan: add ISO CAN FD feature support
-
-ISO CAN FD is introduced to increase the failture detection capability
-than non-ISO CAN FD. The non-ISO CAN FD is still supported by FlexCAN so
-that it can be used mainly during an intermediate phase, for evaluation
-and development purposes.
-
-Therefore, it is strongly recommended to configure FlexCAN to the ISO
-CAN FD protocol by setting the ISOCANFDEN field in the CTRL2 register.
-
-NOTE: If you only set "fd on", driver will use ISO FD mode by default.
-You should set "fd-non-iso on" after setting "fd on" if you want to use
-NON ISO FD mode.
