Staging: sep: kick out various fields we can prove are not needed 



#1: sep->cache_addr is assigned to sep->rar_addr and never changed
    sep->rar_addr is never assigned after this point

#2: sep->cache_bus ditto for sep->rar_bus

#3  sep->rar_region_addr is assigned but necer used

#4  sep->io_addr is in fact private to the probe function and
    the same as the reg_addr

#5  The remainig sep->io fields are in fact function locals

#6  sep->message_shared_area is assigned once from sep->shared_area
    sep->shared_area does not then change

#7  sep->shared_addr and sep->shared_area_addr are the same thing, ditto
    for the bus addresses.
