[PATCH V2 4/4] pinctrl: add one more "const" for generic function groups

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

Generic code doesn't modify those strings and .get_function_groups
callback has that extra "const" as well. This allows more flexibility in
GENERIC_PINMUX_FUNCTIONS users.
