[PATCH v4 1/3] dt-bindings: i3c: dw: Describe core reset

The "core_rst" reset support has been in the code from day1, but the
dt-binding doesn't exist. Add dt-binding to describe reset property.

Then why not remove the "_rst" suffix? Krzysztof pointed out "Cleanup
of name is not really worth affecting users. core_rst is not the best
name but it is not incorrect, either."
