pinctrl: tegra: Fix off by one in tegra_pinctrl_get_group()
commit 5a062c3c3b82004766bc3ece82b594d337076152 upstream.
This should be >= pmx->soc->ngroups instead of > to avoid an out of
bounds access. The pmx->soc->groups[] array is allocated in
tegra_pinctrl_probe().
Fixes: c12bfa0fee65 ("pinctrl-tegra: Restore SFSEL bit when freeing pins")
