drm/radeon: fix regression on atom cards with hardcoded EDID record.
commit eaa4f5e1d0b816291a59a47917e569c0384f2b6f upstream.
Since fafcf94e2b5732d1e13b440291c53115d2b172e9 introduced an edid size, it seems to have broken this path.
This manifest as oops on T500 Lenovo laptops with dual graphics primarily.
