dmaengine: at_hdmac: use %pad format string for dma_addr_t

dma_addr_t may be defined as 32 or 64 bit depending on configuration,
so it cannot be printed using the normal format strings, as
gcc correctly warns:

drivers/dma/at_hdmac.c: In function 'atc_prep_dma_interleaved':
drivers/dma/at_hdmac.c:731:28: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=]

This changes the format strings to use the special "%pad" format
string that prints a dma_addr_t, and changes the arguments so we
pass the address by reference as required.
