[PATCH v2 1/4] dt-bindings: reset: nuvoton,ma35d1-reset: add simple-mfd and child node support

[Joey Lu <a0987203069@gmail.com>]

The MA35D1 system-management syscon node hosts the USB PHY register
block at offset 0x60.  To model usb-phy@60 as a DT child of the syscon
node the binding must allow:

  - simple-mfd as an optional third compatible so the MFD core can
    instantiate child platform devices.

  - #address-cells and #size-cells (each const: 1) so child nodes can
    carry a reg property.

  - An open child-node pattern (patternProperties "^.*@[0-9a-f]+$")
    to pass dt-schema validation.
