[PATCH] drm/exynos/fimd: fix register offset type in fimd_trigger()

[Chen-Yu Tsai <wenst@chromium.org>]

Sparse reports:

    exynos_drm_fimd.c:992:39: warning: incorrect type in initializer (different address spaces)
    exynos_drm_fimd.c:992:39:    expected void *timing_base
    exynos_drm_fimd.c:992:39:    got void [noderef] __iomem *
    exynos_drm_fimd.c:1005:33: warning: incorrect type in argument 1 (different address spaces)
    exynos_drm_fimd.c:1005:33:    expected void const volatile [noderef] __iomem *addr
    exynos_drm_fimd.c:1005:33:    got void *
    exynos_drm_fimd.c:1007:33: warning: incorrect type in argument 2 (different address spaces)
    exynos_drm_fimd.c:1007:33:    expected void volatile [noderef] __iomem *addr
    exynos_drm_fimd.c:1007:33:    got void *

Add "__iomem" to *timing_base to fix its type.
