dmaengine: apple-admac: Fix print format

We get a warning (treated as error now)
drivers/dma/apple-admac.c: In function 'admac_cyclic_write_one_desc':
drivers/dma/apple-admac.c:209:26: error: format '%x' expects argument of type 'unsigned int', but argument 7 has type 'long unsigned int' [-Werror=format=]
  209 |         dev_dbg(ad->dev, "ch%d descriptor: addr=0x%pad len=0x%zx flags=0x%x\n",

Use %lx for priniting the flag
