[PATCH] arm: mvebu: Fix pinctrl for Armada 370 Mirabox SDIO port.

[Ryan Press]

The previous configuration used the wrong "clk" pin.  Without this change mv_sdio worked because the bootloader would set the pin up, but with a bootloader that does not set the pin, mv_sdio fails to detect any card.

I have tested this change using a mwifiex_sdio wireless network adapter over the SDIO interface.
