[PATCH 20/21] media: fsl-viu: fix __iomem annotations

[Mauro Carvalho Chehab]

Those annotations are wrong, causing this warning:

    drivers/media/platform/fsl-viu.c:1440:21: warning: incorrect type in 
assignment (different address spaces)
    drivers/media/platform/fsl-viu.c:1440:21:    expected struct viu_reg *vr
    drivers/media/platform/fsl-viu.c:1440:21:    got struct viu_reg [noderef] 
<asn:2>*[assigned] viu_regs
