[PATCH v2 12/20] arm: kirkwood: dreamplug: use Device Tree to probe SDIO

[Thomas Petazzoni]

Now that the mvsdio driver has a Device Tree binding, and the SDIO
controller is declared in kirkwood.dtsi, migrate the dreamplug board
to use the Device Tree to probe the SDIO controller and to mux this
interface properly.

Changes since v1:
 * Remove the useless header inclusion from board-dreamplug.c, now
   that the SDIO interface is probed from the Device Tree.
 * Reference the pmx_sdio muxing option from the DT node describing
   the SDIO interface, in order to get proper muxing of this
   interface.
