[PATCH v3 07/32] pinctrl: mediatek: mt7988: Enable module build support

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: 08bec8511182 ("pinctrl: mediatek: add MT7988 pinctrl driver")
