[PATCH 3/3] drm/exynos: clone new sgt instead of creating from pages

During map_dma_buf, a new sgt needs to be created before being mapped to another device's address space. Currently, this sgt is created from the pages of the gem buffer everytime by calling dma_get_sgtable. This will be time consuming if the map/unmap calls are done repeatedly for very large buffer
