Subject: [PATCH v1 0/5] Improve MediaTek pinctrl v2 and make backward compatible to smartphone mass production usage

This patch improves MediaTek pinctrl v2 and makes backward compatible to
current smartphone mass production usage by:
1.Check gpio pin number and use binary search in control address lookup
2.Supporting driving setting without mapping current to register value
3.Correct usage of PIN_CONFIG get/set implementation
4.Backward compatible to previous Mediatek's bias-pull usage
5.Add support for pin configuration dump via sysfs
