[PATCH 04/12] drm/radeon: remove radeon_connector_edid() and stop using edid_blob_ptr

[Jani Nikula <jani.nikula@intel.com>]

radeon_connector_edid() copies the EDID from edid_blob_ptr as a side
effect if radeon_connector->edid isn't initialized. However, everywhere
that the returned EDID is used, the EDID should have been set
beforehands.

Only the EDID code and sysfs should look at the EDID property, anyway,
so stop using it.
