drm/exynos: Use fbdev DMA helpers
Use fbdev's DMA helpers for fbdev emulation. The driver previously
used the I/O-memory helpers, while allocating DMA-able system memory.
This could (in theory) result in bus errors from accessing the memory
range.
This bug has been present since the exynos driver was first added.
v2:
* drop the pointless Fixes tag (Javier)
* fix typo in commit message
