drm/exynos: remove 'pages' and 'page_size' elements in exynos gem buffer
Changelog v2: Removed redundant check for invalid sgl. Added check for valid page_offset in the beginning of exynos_drm_gem_map_buf. Changelog v1: The 'pages' structure is not required since we can use the 'sgt'. Even for CONTIG buffers, a SGT is created (which will have just one sgl). This SGT can be used during mmap instead of 'pages'. The 'page_size' element of the structure is also not used anywhere and is removed. This patch also fixes a memory leak where the 'pages' structure was being allocated during gem buffer allocation but not being freed during deallocate.
