Propsed patch for reference

Ph52a PCIE to SATA card inserted on Intel MTL/ARL causes system hanging with AMI code base. The issue is not there on previous Intel platform RPL because Intel uses SataControl code in its platform package with the fix attached.

Root cause of this issue is because Ph52a's driver only uses DevicePath protocol alone and EDK2 driver only uses PciIo protocol alone. Both drivers start and try to manage SATA controller.

To avoid seeing same issue with difference card vendor in the future, we are hoping EDK2 group can take this fix generically.

Provide AMI Internal ticket EIP803584 for reference.
