pinctrl: ingenic: Put ingenic_chip_info pointer in match data

Instead of passing a numeric ID as match data, and retrieve a pointer to
the ingenic_chip_info structure in an ugly succession of if/else in the
probe function, get the pointer to the ingenic_chip_info structure
directly from the match data, and store the numeric ID inside the
ingenic_chip_info structure.
