We don't have the UFS card slot on the sa8540p exposed. However, it is
available on the sa8295p.

The original DTS in upstream listed 230 pins, however pinctrl-sc8280xp.c
lists 233 pins and the two UFS pins match what we have in DTS.

static const struct pinctrl_pin_desc sc8280xp_pins[] = {
        PINCTRL_PIN(0, "GPIO_0"),
	...
	PINCTRL_PIN(227, "GPIO_227"),
	PINCTRL_PIN(228, "UFS_RESET"),
	PINCTRL_PIN(229, "UFS1_RESET"),
	PINCTRL_PIN(230, "SDC2_CLK"),
	PINCTRL_PIN(231, "SDC2_CMD"),
	PINCTRL_PIN(232, "SDC2_DATA"),
