[PATCH] dt-bindings: i3c: dw: Document missing optional core reset

The DesignWare I3C master IP supports a core reset input, but the
binding is missing the corresponding reset description.

Document the reset property and name in the binding. Keep the reset
optional because the reset line is integration-specific..

Note:
The DesignWare I3C driver support was added by
1dd728f5d4d4 ("i3c: master: Add driver for Synopsys DesignWare IP").

The original Synopsys DesignWare I3C binding was added by
116e246a8bcd ("dt-binding: i3c: Document Synopsys DesignWare I3C"),
but it did not document the optional core reset.
