ipq806x: remove support for kernel 4.19

The target uses 5.4 as default kernel since 04/2020.

Kernel 4.19 support is not really maintained anymore, and there has
been a lot of changes between 4.19 and 5.4 on this target. Despite,
new devices are typically added for 5.4 only anyway.

Thus, make maintaining of old stuff and reviewing of new stuff
easier by removing support for kernel 4.19.

-+High-Frequency PLL (HFPLL)
-+
-+PROPERTIES
-+
-+- compatible:
-+	Usage: required
-+	Value type: <string>:
-+		shall contain only one of the following. The generic
-+		compatible "qcom,hfpll" should be also included.
-+
-+                        "qcom,hfpll-ipq8064", "qcom,hfpll"
-+                        "qcom,hfpll-apq8064", "qcom,hfpll"
-+                        "qcom,hfpll-msm8974", "qcom,hfpll"
-+                        "qcom,hfpll-msm8960", "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
-+		    register region.
-+
-+- clocks:
-+	Usage: required
-+	Value type: <prop-encoded-array>
-+	Definition: reference to the xo clock.
-+
-+- clock-names:
-+	Usage: required
-+	Value type: <stringlist>
-+	Definition: must be "xo".
-+
-+- 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-ipq8064", "qcom,hfpll";
-+		reg = <0xf9016000 0x30>;
-+		clocks = <&xo_board>;
-+		clock-names = "xo";
-+		clock-output-names = "hfpll_l2";
-+	};
-+
-+2) An HFPLL for CPU0. This HFPLL has the alias register region.
-+
-+	clock-controller@f908a000 {
-+		compatible = "qcom,hfpll-ipq8064", "qcom,hfpll";
-+		reg = <0xf908a000 0x30>, <0xf900a000 0x30>;
-+		clocks = <&xo_board>;
-+		clock-names = "xo";
-+		clock-output-names = "hfpll0";
-+	};
