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 650/660] net: phylink: support Clause 45 PHYs on SFP+ modules
-
-Some SFP+ modules have Clause 45 PHYs embedded on them, which need a
-little more handling in order to ensure that they are correctly setup,
-as they switch the PHY link mode according to the negotiated speed.
-
-With Clause 22 PHYs, we assumed that they would operate in SGMII mode,
-but this assumption is now false.  Adapt phylink to support Clause 45
-PHYs on SFP+ modules.
