drm/exynos: consider buffer allocation without iommu
This patch fixes the issue that when buffer allocation is requested
without iommu, the allocation is failed.
Without iommu, dma_alloc_attrs function allocates some memory region
and returns cpu address so this patch makes the cpu address to be set
to buf->kvaddr correctly.
Changelog v2:
- fix buffer free
. Without iommu, dma_free_attrs function requires kernel space address
as argument. So it changes the argument, buf->pages to buf->kvaddr.
