drm/exynos: use __free_page() to deallocate memory
this patch uses __free_page() to deallocate the pages allocated
by alloc_page() and the pages doesn't need set_parge_dirty()
and mark_page_accessed() because they aren't from page cache so
removes them.
this patch has a pair with previous patch below,
http://www.spinics.net/lists/dri-devel/msg24382.html
Changelog v2:
remove unnecessary arguments.
Changelog v3:
fix npages type.
- npages can have negative value.
