dmaengine: imx-dma: Cast of_device_get_match_data() with (uintptr_t)

Change the of_device_get_match_data() cast to (uintptr_t)
to silence the following clang warning:

drivers/dma/imx-dma.c:1048:20: warning: cast to smaller integer type 'enum imx_dma_type' from 'const void *' [-Wvoid-pointer-to-enum-cast]
