From: Randy Dunlap <rdunlap@...radead.org>

[ Upstream commit 047cd9a6bd8a2a73e8d92eb97a1b50c7bcd59279 ]

Export mtk_is_virt_gpio() for the case when
CONFIG_PINCTRL_MTK=y
CONFIG_PINCTRL_MTK_V2=y
CONFIG_PINCTRL_MTK_MOORE=y
CONFIG_PINCTRL_MTK_PARIS=m

to fix this build error:

ERROR: modpost: "mtk_is_virt_gpio" [drivers/pinctrl/mediatek/pinctrl-paris.ko] undefined!
