This patch introduces a data structure mtk_pin_desc, which is used to provide information per pin characteristic such as driving current, eint number and a driving index, that is used to lookup table describing the details about the groups of driving current by which the pin is able to adjust the driving strength so that the driver could get the appropriate driving group when calls .pin_config_get()/set().
