regulator: mt6360: De-capitalize devicetree regulator subnodes

The MT6360 regulator binding, the example in the MT6360 mfd binding, and
the devicetree users of those bindings are rightfully declaring MT6360
regulator subnodes with non-capital names, and luckily without using the
deprecated regulator-compatible property.

With this driver declaring capitalized BUCKx/LDOx as of_match string for
the node names, obviously no regulator gets probed: fix that by changing
the MT6360_REGULATOR_DESC macro to add a "match" parameter which gets
assigned to the of_match.
