[PATCH v3 15/19] imx: kontron-sl-mx8mm: Use the VSELECT signal to switch SD card IO voltage

[sbabic at denx.de]

> From: Frieder Schrempf <frieder.schrempf at kontron.de>
> It turns out that it is not necessary to declare the VSELECT signal as
> GPIO and let the PMIC driver set it to a fixed high level. This switches
> the voltage between 3.3V and 1.8V by setting the PMIC register for LDO5
> accordingly.
> Instead we can do it like other boards already do and simply mux the
> VSELECT signal of the USDHC interface to the pin. This makes sure that
> the correct voltage is selected by setting the PMIC's SD_VSEL input
> to high or low accordingly.
