[PATCH v4 30/32] pinctrl: mediatek: mt2712: Enable module build support

[Justin Yeh]

Add MODULE_LICENSE("GPL v2") 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: 8670710ff8fe ("pinctrl: mediatek: Add Mediatek MT2712 pinctrl driver")
