[PATCH] drm/bridge: anx7625: Fix EDID block size at drm_edid_alloc() calling

[Xin Ji]

Since DRM validates the all of EDID blocks, allocates drm_edid data
structure based on the actually block count returned by the sink
monitor at drm_edid_alloc() calling.

Fixes: 7c585f9a71aa ("drm/bridge: anx7625: use struct drm_edid more")
