drm/exynos: add iommu support for g2d
Chagelog v2:
removed unnecessary structure, struct g2d_gem_node.
Chagelog v1:
This patch adds iommu support for g2d driver. For this, it
adds subdrv_probe/remove callback to enable or disable
g2d iommu. And with this patch, in case of using g2d iommu,
we can get or put device address to a gem handle from user
through exynos_drm_gem_get/put_dma_addr(). Actually, these
functions take a reference to a gem handle so that the gem
object used by g2d dma is released properly.
And runqueue_node has a pointer to drm_file object of current
process to manage gem handles to owner.
This patch is based on the below patch set, "drm/exynos: add
iommu support for -next".
