ipq806x: remove support for kernel 4.14

This target has been on kernel 4.19 for several months [1] and
already uses kernel 5.4 as testing kernel. Therefore, it should
not be necessary to keep support for kernel 4.14 as well.

-
-On some devices (MSM8974 for example), the HFPLLs are
-instantiated within the Krait processor subsystem as separate
-register regions. Add a driver for these PLLs so that we can
-provide HFPLL clocks for use by the system.

-+High-Frequency PLL (HFPLL)

-+PROPERTIES
-+
-+- compatible:
-+	Usage: required
-+	Value type: <string>
-+	Definition: must be "qcom,hfpll"
-+
-+- reg:
-+	Usage: required
-+	Value type: <prop-encoded-array>
-+	Definition: address and size of HPLL registers. An optional second
-+		    element specifies the address and size of the alias

-+
-+- clock-output-names:
-+	Usage: required
-+	Value type: <string>
-+	Definition: Name of the PLL. Typically hfpllX where X is a CPU number
-+		    starting at 0. Otherwise hfpll_Y where Y is more specific
-+		    such as "l2".
-+
-+Example:
-+
-+1) An HFPLL for the L2 cache.
-+
-+	clock-controller@f9016000 {
-+		compatible = "qcom,hfpll";
-+		reg = <0xf9016000 0x30>;
-+		clock-output-names = "hfpll_l2";
-+	};
-+
-+2) An HFPLL for CPU0. This HFPLL has the alias register region.
-+
-+	clock-controller@f908a000 {
-+		compatible = "qcom,hfpll";
-+		reg = <0xf908a000 0x30>, <0xf900a000 0x30>;
