[U-Boot] [U-Boot, v4, 35/66] rockchip: pinctrl: rk3368: add support for configuring the MMC pins

[Philipp Tomsich]

> The RK3368 has two SD/MMC controllers that can be used from U-Boot
> both during SPL and for booting an OS from the full bootloader stage.
> While both are configured to (mostly) sensible settings from the BROM,
> additional configuration for the MMC controller is needed to configure
> it to 8bit mode.

> This adds pinctrl support for the MMC controller.
