[PATCH 2/9] dmaengine: edma: Use enum for eDMA binding type (legacy vs TPCC)

[Peter Ujfalusi]

Fixes the following warning when compiling the driver for 64bit
architectures (x86_64 for example):
drivers/dma/edma.c:2185:16: warning: cast from pointer to integer of different 
size [-Wpointer-to-int-cast]
   if (match && (u32)match->data == EDMA_BINDING_TPCC)
                ^
