[PATCH] drm/exynos: fix memory leak: free EDID block

[Egbert Eich <eich@suse.de>]

drm_get_edid() returns a pointer to an EDID block. The caller
is responsible to free this pointer itself.
Here the pointer gets assigned to the local variable raw_edid.
Therefore it should be freed before the variable goes out of
scope.
