[PATCH 1/2] media: platform: fsl-viu: add __iomem annotations

[Arnd Bergmann]

This avoids countless sparse warnings like

   drivers/media/platform/fsl-viu.c:1081:25: sparse: incorrect type in argument 2 (different address spaces)
   drivers/media/platform/fsl-viu.c:1082:25: sparse: incorrect type in argument 2 (different address spaces)
