scc_pata: kill unused variables 



Fix the "unused variable" warning in init_hwif_scc() caused by the commit
48c3c107 (ide: add struct ide_host (take 3)).
Moreover, remove the write-only variable 'dma_status_port' in init_setup_scc()
about which gcc gives no warning and which has been there from the very start...
