gemini: Remove kernel 4.14 support

This target was switched to kernel 4.19 more than 6 months ago in commit
f342ffd300da ("treewide: kernel: bump some targets to 4.19") and now
with kernel 5.4 support being added it gets harder to support kernel
4.14 in addition to kernel 4.19 and 5.4.

-Subject: [PATCH 04/31] pinctrl: Add skew-delay pin config and bindings
-
-Some pin controllers (such as the Gemini) can control the
-expected clock skew and output delay on certain pins with a
-sub-nanosecond granularity. This is typically done by shunting
-in a number of double inverters in front of or behind the pin.
-Make it possible to configure this with a generic binding.
