As a first step to separate the platform_data code from the
devicetree code add a function to parse the boarddata. Also
change the argument of the dt probe function from
struct esdhc_platform_data * to struct pltfm_imx_data *imx_data
which makes it possible to get struct esdhc_platform_data out
of the devicetree probing path.
