EISA has absolutely nothing to do with traps, so move it out of traps.c into its own eisa.c file. Furthermore, the EISA bus detection does not need to run during very early boot, it's good enough to run it before the EISA bus and drivers are initialized. I.e. instead of calling it from the very early trap_init() code, make it a subsys_initcall().
