[PATCH RTEMS 3/7] libfreebsd: Added ofw_if.h

[G S Niteesh Babu]

This file is the RTEMS implementation of ofw_if.h in FreeBSD. The
ofw_if.h in FreeBSD is an autogenerated header file that maps the
OF_function calls to their respective implementation. But in RTEMS
this file maps the OF_functions directly to their FDT implementation.
