Pin groups are per definiton per-controller inctance. That is a given side effect of not having a global pin space.
But you can create two groups of the same name on two pin controllers so that e.g. pinctrl.0 and pinctrl.1 have a group named "foo", then map both to a certain device in the board pinmux map.
You will have to request them individually however, like with two hogs or two pinmux_get() calls specifying the name of each map, else you will just get the first one.
Not that I've tried it, but that's how it's supposed to work...
