My Questions：
1. As you can see GPIO1_IO04 already mux for VSELECT not for GPIO. so why "pinctrl-assert-gpios = <&gpio1 4 GPIO_ACTIVE_HIGH>" can be set in usdhc2 node?
2. what is the purpose seting "pinctrl-assert-gpios = <&gpio1 4 GPIO_ACTIVE_HIGH>"? and will the sdhc driver not operate VSELECT through bit[VSELECT ] of register SDHCx_VEND_SPEC?
