[PATCH v2 1/1] PCI: mediatek: Correct type for virt_to_phys()

[Andy Shevchenko]

virt_to_phys() takes a regular pointer, while driver supplies __iomem
annotated one. Force type to void to make sparse happy, otherwise

   pcie-mediatek.c:400:40: sparse:     expected void volatile *address
   pcie-mediatek.c:400:40: sparse:     got void [noderef] __iomem *

   pcie-mediatek.c:523:44: sparse:     expected void volatile *address
   pcie-mediatek.c:523:44: sparse:     got void [noderef] __iomem *
