drm/exynos: use DMA_ATTR_NO_KERNEL_MAPPING attribute
Changelog v3:
just code cleanup.
Changelog v2:
fix argument to dma_mmap_attr function.
- use pages instead of kvaddr because kvaddr is 0 with
DMA_ATTR_NO_KERNEL_MAPPING.
Changelog v1:
When gem allocation is requested, kernel space mapping isn't needed.
But if need, such as console framebuffer, the physical pages would be
mapped with kernel space though vmap function.
