pinctrl: mediatek: fix handling return value of mtk_pmx_find_gpio_mode
The function can return negative values, so its result should
be assigned to signed variable.
The problem has been detected using coccinelle semantic patch
scripts/coccinelle/tests/assign_signed_to_unsigned.cocci.
Fixes: 59ee9c9 ('pinctrl: mediatek: Add gpio_request_enable support')
