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 622/660] net: sfp: rename T_PROBE_WAIT to T_SERIAL
-
-SFF-8472 rev 12.2 defines the time for the serial bus to become ready
-using t_serial.  Use this as our identifier for this timeout to make
-it clear what we are referring to.
