On command completion, ata_qc_complete() directly called ops->tf_read to fill qc->result_tf. This patch adds ops->qc_fill_rtf to replace hardcoded ops->tf_read usage. ata_sff_qc_fill_rtf() which uses ops->tf_read to fill result_tf is implemented and set in ata_base_port_ops and other ops tables which don't inherit from ata_base_port_ops, so this patch doesn't introduce any behavior change. ops->qc_fill_rtf() is similar to ops->sff_tf_read() but can only be called when a command finishes. As some non-SFF controllers don't have TF registers defined unless they're associated with in-flight commands, this limited operation makes life easier for those drivers and help lifting SFF assumptions from libata core layer.
