[PATCH 2/2] dt-bindings: arm: vexpress: drop the obsolete hwmon and regulator text files

[Quchaosheng]

Documentation/devicetree/bindings/hwmon/vexpress.txt describes the
arm,vexpress-volt, -amp, -temp, -power and -energy sensors, and
Documentation/devicetree/bindings/regulator/vexpress.txt describes the
arm,vexpress-volt regulator.

Both restate what arm/vexpress-config.yaml already documents: the same
compatibles, the arm,vexpress-sysreg,func property and the label property.
The regulator node refers to regulator.yaml, which covers the generic
regulator properties the second file lists, and all 13 in-tree
arm,vexpress-volt nodes set both of the properties it calls required.

One sentence in the regulator file is not a restatement: it says that a
supply without regulator-min-microvolt and regulator-max-microvolt is
treated as fixed. vexpress_regulator_probe() implements that by selecting
vexpress_regulator_ops_ro when the two properties do not both define a
range. Move the note into the regulator node description in the schema,
so that removing the file does not lose it.

Nothing else refers to the two files. Remove them.
