[PATCH v2] x86/setup: Make setup.h header self contained

[Frediano Ziglio <frediano.ziglio@xxxxxxxxx>]

The header uses rangeset structure pointer.
Forward declare the structure.

Signed-off-by: Frediano Ziglio <frediano.ziglio@xxxxxxxxx>

Changes since v1:
- use structure forward declaration instead of including header.
