kernel: remove support for kernel 4.19

We use 5.4 on all targets by default, and 4.19 has never been released
in a stable version. There is no reason to keep it.

-Subject: [PATCH 621/660] net: sfp: handle module remove outside state machine
-
-Removing a module resets the module state machine back to its initial
-state.  Rather than explicitly handling this in every state, handle it
-early on outside of the state machine.
