dmaengine: sa11x0: use correct print specifiers for dma_addr_t

This driver when compiled on 64 bits gave warnings:

drivers/dma/sa11x0-dma.c:466:27: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'dma_addr_t' [-Wformat=]
drivers/dma/sa11x0-dma.c:554:31: warning: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t' [-Wformat=]
drivers/dma/sa11x0-dma.c:696:34: warning: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t' [-Wformat=]

We should use %pad to print 'dma_addr_t' values.
