[PATCH v3] OvmfPkg: Call PlatformInitializeConsole for GPU passthrough case

["Stefan Berger" <stefanb@linux.ibm.com>]

For GPU passthrough support we have to initialize the console after
EfiBootManagerDispatchDeferredImages() has loaded ROMs, so call it after
this. This was the calling order before the TCG physical presence support
had to be moved and the console initialized earlier so user interaction
could be supported before processing TCG physical presence opcodes.
