The value of MAX_EDID is now valid only for 2
block EDID data which is 256, but to support
4 block EDID (E-DDC) this needs to be 512.
Based on drm-next branch

Shouldn't this be in a common drm/edid header to begin with?

This value is not real maximum length of EDID and it is only used for
memory allocation by exynos connector. Actually, this allocation is
unnecessary because edid is already allocated by drm_get_edid().
So, I have plan to remove this allocation and the definition once Jani
Nikula's patches for removing raw_edid related memory leaks are applied.

this modification is required,hence i thought of posting this patch.
