dmaengine: dw-edma: Drop unnecessary debugfs reg casts

The debugfs_entries structure declared in dw-edma-v0-debugfs.c contains the
debugfs node register address. The address is declared as dma_addr_t type,
but is cast to "void *".

Change the type to "void __iomem *" and drop the unnecessary casts.
