Subject: [PATCH] [media] drm/exynos: Convert g2d_userptr_get_dma_addr() to use
 get_vaddr_frames()

Convert g2d_userptr_get_dma_addr() to pin pages using get_vaddr_frames().
This removes the knowledge about vmas and mmap_sem locking from exynos
driver. Also it fixes a problem that the function has been mapping user
provided address without holding mmap_sem.
