Your hardware is not appropriate for the MacPro5,1 SMBIOS.I attached my previously working EFI folder. This used to boot up like a charm.
See if this config.plist makes any difference :
Edit : You should probably delete NullCPUPowerManagement.kext as it is at odds with your efforts at power management.
