drm/exynos: Add fallback option to get non physically contiguous memory for fb
While trying to get boot-logo up on exynos5420 SMDK which has eDP panel
connected with resolution 2560x1600, following error occured even with
IOMMU enabled:
[0.880000] [drm:lowlevel_buffer_allocate] *ERROR* failed to allocate buffer.
[0.890000] [drm] Initialized exynos 1.0.0 20110530 on minor 0
To address the cases where physically contiguous memory MAY NOT be a
mandatory requirement for fb, the patch adds a feature to get non physically
contiguous memory for fb if physically contiguous memory allocation fails
and if IOMMU is supported.
