Subject: [PATCH net-next 02/10] dt-bindings: net: ocelot: remove hsio from the list of register address spaces

HSIO register address space should be handled outside of the MAC
controller as there are some registers for PLL5 configuring,
SerDes/switch port muxing and a thermal sensor IP, so let's remove it.

+o HSIO regs:
+
+The SoC has a few registers (HSIO) handling miscellaneous functionalities:
+configuration and status of PLL5, RCOMP, SyncE, SerDes configurations and
+status, SerDes muxing and a thermal sensor.
+
+Required properties:
+- compatible: Should be "mscc,ocelot-hsio", "syscon", "simple-mfd"
+- reg : Should contain registers location and length
+
+Example:
+	syscon@...0000 {
+		compatible = "mscc,ocelot-hsio", "syscon", "simple-mfd";
+		reg = <0x10d0000 0x10000>;
