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.
