dmaengine: ti-dma-crossbar: Fix of_device_id data parameter usage
Use pointers to static constant variables for crossbar type and for DMA
offset configuration.
Fixes compiler warnings on 64bit architectures:
drivers/dma/ti-dma-crossbar.c: In function ‘ti_dra7_xbar_probe’:
drivers/dma/ti-dma-crossbar.c:398:21: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
xbar->dma_offset = (u32)match->data;
^
drivers/dma/ti-dma-crossbar.c: In function ‘ti_dma_xbar_probe’:
drivers/dma/ti-dma-crossbar.c:431:10: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
switch ((u32)match->data) {
