[PATCH v2 05/32] pinctrl: mediatek: mt7981: 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: 6c83b2d94fcc ("pinctrl: add mt7981 pinctrl driver")
