[PATCH] fsldma: Fix compile warnings

[Kumar Gala]

We we build with dma_addr_t as a 64-bit quantity we get:

drivers/dma/fsldma.c: In function 'fsl_chan_xfer_ld_queue':
drivers/dma/fsldma.c:625: warning: cast to pointer from integer of different size

drivers/dma/fsldma.c: In function 'of_fsl_dma_probe':
