Move the printers to the respective files for clarity. The
guc_load_status debugfs has been squashed in the guc_info one, has
having separate ones wasn't very useful. The HuC debugfs has been
renamed huc_info to match.
v2: keep printing HUC_STATUS2 (Tony), avoid const->non-const
container_of (Jani)
