For some fields the use of struct exynos_drm_plane filled with data from
the plane state just creates a source of duplicated information and
overhead. Here we change the crtc drivers to access the plane state
directly simplifying the code by not relying on a exynos internal struct.

We already have the plane pointer in before calling .update_plane() or
disable_plane() so pass it directly to those calls avoiding a new
conversion from zpos to struct exynos_drm_plane.

Get rid of legacy DRM vblank function that are less clear to use.
The new ones basically requires only the crtc as parameters.
It also clean ups exynos_drm_crtc_finish_pageflip() parameters as a
consequence.

Already drm_iommu_attach_device checks whether support iommu internally.
It should clear channels always regardless iommu support. We didn't know
because we can detect the problem when iommu is enabled, so we don't
have to use drm_iommu_attach_device_if_possible and then we can remove
drm_iommu_attach_device_if_possible and clear_channels function pointer.

Already drm_iommu_attach_device and drm_iommu_detach_device check
whether support iommu internally, so we don't have to call
is_drm_iommu_supported before call them.
