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. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

-Subject: [PATCH 16/18] usb: host: fotg2: add Gemini-specific handling
-
-The Cortina Systems Gemini has bolted on a PHY inside the
-silicon that can be handled by six bits in a MISC register in
-the system controller.
-
-If we are running on Gemini, look up a syscon regmap through
-a phandle and enable VBUS and optionally the Mini-B connector.
-
-If the device is flagged as "wakeup-source" using the standard
-DT bindings, we also enable this in the global controller for
-respective port.
