Ranbir Singh ae6e470252 MdeModulePkg/Bus/Ata/AhciPei: Fix DEADCODE Coverity issue
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4201

The code can reach line 69 only through the else path above at line 57.
The else path already has the same NULL check at line 59 and hence the
duplicate code lines are totally redundant which can be deleted.

Hao Wu 87bc3f192e MdeModulePkg/AhciPei: Add AHCI mode ATA device support in PEI
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1409

This commit will add the AHCI mode ATA device support in the PEI phase.

More specifically, the newly add AhciPei driver will consume the ATA AHCI
host controller PPI for ATA controllers working under AHCI code within the
system. And then produces the below PPIs for each controller:

EDKII PEI ATA PassThru PPI
Storage Security Command PPI

Also, the driver will consume the S3StorageDeviceInitList LockBox in S3
phase. The purpose is to perform an on-demand (partial) ATA device
enumeration/initialization on each controller to benefit the S3 resume
performance.

The implementation of this driver is currently based on the below
specifications:
Serial ATA Revision 2.6
Serial ATA Advanced Host Controller Interface (AHCI) 1.3.1
AT Attachment with Packet Interface - 6 (ATA/ATAPI-6)
