pinctrl: mediatek: fix static checker warning caused by EINT_NA
EINT_NA is an u16 number, so it should be U16_MAX instead of -1
to fix up drivers/pinctrl/mediatek/pinctrl-paris.c:732 mtk_gpio_to_irq()
warn: impossible condition (desc->eint.eint_n == -1) => (0-u16max == (-1))
Also happens in
drivers/pinctrl/mediatek/pinctrl-paris.c:749 mtk_gpio_set_config()
warn: impossible condition (desc->eint.eint_n == -1) => (0-u16max == (-1))
drivers/pinctrl/mediatek/pinctrl-moore.c:479 mtk_gpio_to_irq()
warn: impossible condition (desc->eint.eint_n == -1) => (0-u16max == (-1))
drivers/pinctrl/mediatek/pinctrl-moore.c:496 mtk_gpio_set_config()
warn: impossible condition '(desc->eint.eint_n == -1) => (0-u16max == (-1))
