A dma_addr_t is not a pointer and a cast causes a warning when
the sizes are different:

sound/soc/bcm/bcm63xx-pcm-whistler.c: In function 'bcm63xx_pcm_pointer':
sound/soc/bcm/bcm63xx-pcm-whistler.c:184:6: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
  184 |  if ((void *)prtd->dma_addr_next == NULL)

Change the comparison to NULL to an equivalent if() check that
does not warn.
