To support running ccp_server (works as EGL stream consumer) on Linux VM
on CCC, we need to add the 3rd IVM carveout support (2 are used for 
cross partition EGL stream between Linux and QNX, and between Linux and 
Android.  The 3rd IVM is needed for display server since QNX owns 
display in CCC PCT configuration)
