fsldma: use a valid 'device' for dma_pool_create
The dmaengine sysfs implementation was fixed to support proper
lifetime rules which means that the current:
new_fsl_chan->dev = &new_fsl_chan->common.dev->device;
...retrieves a NULL pointer because new_fsl_chan->common.dev has not
been allocated at this point. So, set new_fsl_chan->dev to a valid
device.
