[PATCH v3 18/32] pinctrl: mediatek: mt2701: Enable module build support

[Justin Yeh]

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: 148b95eea00b ("pinctrl: mediatek: Add Pinctrl/GPIO/EINT driver for mt2701")
