[PATCH v2 08/32] pinctrl: mediatek: mt8167: Enable module build support

[Justin Yeh <justin.yeh@mediatek.com>]

Add MODULE_LICENSE("GPL") macro and change Kconfig option from
bool to tristate to allow building as a loadable kernel module.

This is required for Android GKI + vendor_dlkm deployments where
vendor-specific drivers must be kept separate from the GKI vmlinux.

Fixes: 82d70627e94a ("pinctrl: mediatek: Add MT8167 Pinctrl driver")
