[PATCH 14/18] arm: kirkwood: topkick: 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 topkick board to
use the Device Tree to probe the SDIO controller.

The patch has been tested on the Topkick hardware. However, due to an
apparently unrelated problem, it is unable to detect the Wifi chip
connected on the SDIO bus.
