dt-bindings: i2c: mux: i2c-demux-pinctrl: Define "i2c-parent" constraints

Browse Source 
The 'phandle-array' type is a bit ambiguous. It can be either just an
array of phandles or an array of phandles plus args. "i2c-parent" is
the former and needs to constrain each entry to a single phandle value.
