    Not sure about using platform_get APIs. I think one has to use
    omap_hwmod_get_mpu_rt_va to get the address, which internally returns
    oh-<_mpu_rt_va.
    omap_hwmod_get_mpu_rt_va was added so that the individual drivers can
    avoid doing the ioremap.
    check the discussion regarding this.
