[PATCH v4 06/32] pinctrl: mediatek: mt7986: Enable module build support

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: 360de6728064 ("pinctrl: mediatek: add support for MT7986 SoC")
