REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1409 This commit will add the definitions for EDKII PEI ATA PassThru PPI. This PPI will provide services that allow ATA commands to be sent to ATA devices attached to an ATA controller in the PEI phase. More specifically, the PPI will provide services to: * Send ATA commands to an ATA device (by service 'PassThru'); * Get the list of the attached ATA device on a controller (by services 'GetNextPort' and 'GetNextDevice'); * Get the identification information (DevicePath) of the underlying ATA host controller (by service 'GetDevicePath').
