mav a090de11fd Depending on combination of running commands (NCQ/non-NCQ) try to avoid
extra read from PxCI/PxSACT registers.  If only NCQ commands are running, we
don't really need PxCI.  If only non-NCQ commands are running we don't need
PxSACT.  Mixed set may happen only on controllers with FIS-based switching
when port multiplier is attached, and then we have to read both registers.
