PciPlatform may add some features platform special, like InitAtu and EnlargeAtu for Hi161x, MaxPlayload for Hi1620. So Add two api for expansibility.
This patch is to prepare moving EnlargeAtuConfig0() out of PciHostBridge. Since the function was originally called in NotifyPhase() of phase EfiPciHostBridgeEndEnumeration, so we propose to move it to EFI_PCI_PLATFORM_PROTOCOL->PlatformNotify().
To reduce redundant ATU definitions, we also move InitAtu to PciPlatformLib in Hi161x.
