Applied to clk-next

I noticed that a #define was lost after some revisions for some always
on clk, but I suspect we never care and will never need to turn it on so
I just went with it and dropped it too. Let's cross fingers and hope
that doesn't come back to haunt us!

+Qualcomm LPASS Clock Controller Binding
+-----------------------------------------------
+
+Required properties :
+- compatible		: shall contain "qcom,sdm845-lpasscc"
+- #clock-cells		: from common clock binding, shall contain 1.
+- reg			: shall contain base register address and size,
+			  in the order
+			Index-0 maps to LPASS_CC register region
+			Index-1 maps to LPASS_QDSP6SS register region
+
+Optional properties :
+- reg-names	: register names of LPASS domain
+		 "cc", "qdsp6ss".
+
+Example:
+
+The below node has to be defined in the cases where the LPASS peripheral loader
+would bring the subsystem out of reset.
+
+	lpasscc: clock-controller@17014000 {
+		compatible = "qcom,sdm845-lpasscc";
+		reg = <0x17014000 0x1f004>, <0x17300000 0x200>;
+		reg-names = "cc", "qdsp6ss";
+		#clock-cells = <1>;
+	};
