I changed the patch as you recommended. You were correct, external
declarations are of no use there. At least kernel gets built
successfully both with and without CONFIG_SERIAL_8250 with the patch
applied. Hope it will suit better.

    ppchameleon_early_serial_map hidden under #ifdef CONFIG_SERIAL_8250,
    "extern void gen550_init" and  "extern int early_serial_setup" declarations removed
    since they are already included in header files
