The mtk pinctrl driver is a combination driver with support for both pinctrl and gpio. When this driver is used in SPL, gpio support may not be enabled, and this will result in a compilation error.
To fix this, macros are added to make sure gpio related code will only be compiled when gpio support is enabled.
