MdeModulePkg: SataControllerSupported checks DevicePath Protocol

Browse Source 
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=4858

Ph52a PCIE to SATA card inserted on Intel MTL/ARL causes system hanged.

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.
