Subject: [PATCH v2] pinctrl: mediatek: check mtk_is_virt_gpio input parameter

check mtk_is_virt_gpio input parameter,
virtual gpio need to support eint mode.

add error handler for the ko case
to fix this boot fail:
pc : mtk_is_virt_gpio+0x20/0x38 [pinctrl_mtk_common_v2]
lr : mtk_gpio_get_direction+0x44/0xb0 [pinctrl_paris]

Fixes: edd546465002 ("pinctrl: mediatek: avoid virtual gpio trying to set reg")

Changes since v1:
- update Singed-off-by
- align with pinctrl/mediatek/pinctrl-mtk-mt*.h
