pinctrl: add virtual GPIO "GPIOV_0" for g12a

Browse Source 
PD#162992: pinctrl: add virtual GPIO "GPIOV_0" for g12a

The gpio is used to set the bit PERIPHS_PIN_MUX_2 BIT[17]. Please refer
the following method to use it.

1). set the PERIPHS_PIN_MUX_2 BIT[17] to <1>
mux_en {
	groups = "sdio_dummy";
	function = "sdio";
}

2). set the PERIPHS_PIN_MUX_2 BIT[17] to <0>
mux_dis {
	groups = "GPIOV_0";
	function = "gpio_periphs";
}
