pinctrl: renesas: Add generic support for pin group subsets

It is fairly common for the pins in a pin group to be a subset of the
pins in another pin group.  Add a macro for defining a pin group that
refers to a subset of an array of pins.  This allows pin groups to share
pin data, and thus save memory.
