[PATCH v3 22/32] pinctrl: mediatek: mt8127: 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: 6acdee8c1325 ("pinctrl: mediatek: add pinctrl/GPIO/EINT driver for mt8127")
