[PATCH v4 19/32] pinctrl: mediatek: mt7623: 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: e7507f57a93a ("pinctrl: mediatek: add MT7623 pinctrl driver based on generic pinctrl binding")
