PATCH 1/1 dw_dmac: call .probe after we have a device in place

If we don't yet have the platform device for the driver when it is being loaded we fail to probe the driver. So instead of calling probe() directly we call platform_driver_register(). It will call the probe() immediately if we have the device but also makes the driver to work on platforms where the platform device is created later.
