soc/mediatek/mt8186: Add GPIO driving functions

Add GPIO driving functions to adjust pin driving.

The value of drive strength is different for each SoC, so we define
GPIO_DRV0 to GPIO_DRV7 which are corresponding to 2/4/6/8/10/12/14/16mA
in MT8186.

This implementation is according to chapter 5.1 in MT8186 Functional
Specification.
