ivc: Add wrapper header for ivc.h to avoid multiple inclusion

The ivc.h is not protected for multiple inclusion and so
it is generating error for multiple definition when included
from the source code.

Add wrapper header to protect the multiple inclusion of the ivc.h.

This will make the OOT driers to compile against all core kernel
which does not have proper ivc.h fix.
