Setting a bit in the PxSACT register for a command in the command list indicates
to the controller that the command list slot contains a native queued command (NCQ).
This can cause problems with some controllers (one such controller is the Marvell 9128).
Since NCQ commands are not used, don't set the PxACT register for commands issued.

1. move the non-blocking task related setting ahead to store the MapTable and PageCount in case there is a IO operation error happened then the error handler code could use those information to release the resource.
2. Enlarge the TPL protective area to make sure the simulative delay time is accurate when there is mixing usage of Non blocking and blocking I/O.

1. Boost IDE mode boot when slave device is absent.
2. Use D2H FIS to check if the PIO OUT/DMA IN/DMA OUT transfer is finished or error happened. ATA PIO IN has special check as it may just receive PIO SETUP FIS for success case.
3. Add command status register check for IDE DMA transfer.
4. ScsiDiskReadCapacity() in ScsiDisk should return EFI_SUCCESS if SENSE Data request is success.
