sata: fsl: fix DPRINTK format string

Printing an __iomem pointer as %x produces a warning:

drivers/ata/sata_fsl.c: In function 'fsl_sata_set_irq_coalescing':
drivers/ata/sata_fsl.c:316:17: error: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'void *' [-Werror=format=]
  316 |         DPRINTK("ICC register status: (hcr base: 0x%x) = 0x%x\n",
      |                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  317 |                         hcr_base, ioread32(hcr_base + ICC));
      |                         ~~~~~~~~
      |                         |
      |                         void *

It's not clear why that pointer should be printed here, but if we do,
then using %p is the way to avoid the warnings.
