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 602/660] net: phy: Stop with excessive soft reset
-
-While consolidating the PHY reset in phy_init_hw() an unconditionaly
-BMCR soft-reset I became quite trigger happy with those. This was later
-on deactivated for the Generic PHY driver on the premise that a prior
-software entity (e.g: bootloader) might have applied workarounds in
-commit 0878fff1f42c ("net: phy: Do not perform software reset for
-Generic PHY").
-
-Since we have a hook to wire-up a soft_reset callback, just use that and
-get rid of the call to genphy_soft_reset() entirely. This speeds up
-initialization and link establishment for most PHYs out there that do
-not require a reset.
-
-Fixes: 87aa9f9c61ad ("net: phy: consolidate PHY reset in phy_init_hw()")
