mmc: mvsdio: add pinctrl integration
On many Marvell SoCs, the pins used for the SDIO interface are part of the MPP pins, that are muxable pins. In order to get the muxing of those pins correct, this commit integrates the mvsdio driver with the pinctrl infrastructure by calling devm_pinctrl_get_select_default() during ->probe(). Note that we permit this function to fail because not all Marvell platforms have yet been fully converted to using the pinctrl infrastructure.
