[PATCH v2 21/32] pinctrl: mediatek: mt8135: 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: a6df410d420a ("pinctrl: mediatek: Add Pinctrl/GPIO driver for mt8135.")
