Intel: Add common header file for CAR setup

When passing '-ffreestanding' the 'main' romstage.c may no longer
necessarily be considered the entry point.

From the C specification in 5.1.2.1 Freestanding environment;

"In a freestanding environment (in which C program execution may take
place without any benefit of an operating system), the name and type of
the function called at program startup are implementation-defined."

Clang complains about these being missing as Clang is somewhat more
strict about the spec than GNU/GCC is. An advantage here is that a
different entry-point type-signature shall now be warned about at
compile time.
