Using of_device_get_match_data in imx7d_pinctrl_probe simplifies
the function. Also get rid of the void pointer cast since
imx_pinctrl_probe now accepts const struct imx_pinctrl_soc_info.

For some SoCs the struct imx_pinctrl_soc_info is passed through
of_device_id.data which is const. Most variables are already const
or otherwise not written. However, some fields are modified at
runtime. Move those fields to the dynamically allocated struct
imx_pinctrl.

Pin function can not be match correctly when SUNXI_PIN describe with
mutiple variant and same function.

such as:
on pinctrl-sun4i-a10.c

SUNXI_PIN(SUNXI_PINCTRL_PIN(B, 2),
		SUNXI_FUNCTION(0x0, "gpio_in"),
		SUNXI_FUNCTION(0x1, "gpio_out"),
		SUNXI_FUNCTION_VARIANT(0x2, "pwm",    /* PWM0 */
			PINCTRL_SUN4I_A10 |
			PINCTRL_SUN7I_A20),
		SUNXI_FUNCTION_VARIANT(0x3, "pwm",    /* PWM0 */
			PINCTRL_SUN8I_R40)),

it would always match to the first variant function
(PINCTRL_SUN4I_A10, PINCTRL_SUN7I_A20)

so we should add variant compare on it.

This driver creates a const structure that it stores in the data field
of an of_device_id array.

Adding const to the declaration of the location that receives the
const value from the data field ensures that the compiler will
continue to check that the value is not modified.  Furthermore, the
const-discarding cast on the extraction from the data field is no
longer needed.
