Light Hsieh 3de7deefce pinctrl: mediatek: Check gpio pin number and use binary search in mtk_hw_pin_field_lookup() 
1. Check if gpio pin number is in valid range to prevent from get invalid
   pointer 'desc' in the following code:
	desc = (const struct mtk_pin_desc *)&hw->soc->pins[gpio];

2. Improve  mtk_hw_pin_field_lookup()
2.1 Modify mtk_hw_pin_field_lookup() to use binary search for accelerating
     search.
2.2 Correct message after the following check fail:
    if (hw->soc->reg_cal && hw->soc->reg_cal[field].range) {
		rc = &hw->soc->reg_cal[field];
    The original message is:
    	"Not support field %d for pin %d (%s)\n"
    However, the check is on soc chip level, not on pin level yet.
    So the message is corrected as:
    	"Not support field %d for this soc\n"
