libata: replace tf_read with qc_fill_rtf for non-SFF drivers
Now that all SFF stuff is separated out of core layer, core layer
doesn't call ops->tf_read directly. It gets called only via
ops->qc_fill_rtf() for non-SFF drivers. This patch directly
implements private ops->qc_fill_rtf() for non-SFF controllers and kill
ops->tf_read().
This is much cleaner for non-SFF controllers as some of them have to
cache SFF register values in private data structure and report the
cached values via ops->tf_read(). Also, ops->tf_read() gets nasty for
controllers which don't have clear notion of TF registers when
operation is not in progress.
As this change makes default ops->qc_fill_rtf unnecessary, move
ata_sff_qc_fill_rtf() form ata_base_port_ops to ata_sff_port_ops where
it belongs.
