The "try_all_type" variable is not set if (hw->soc->pull_type) is false
leading to the following Smatch warning:

    drivers/pinctrl/mediatek/pinctrl-paris.c:599 mtk_pctrl_show_one_pin()
    error: uninitialized symbol 'try_all_type'.

Fixes: fb34a9ae383a ("pinctrl: mediatek: support rsel feature")
