nb/intel/i945: Don't rewrite R/WO RCBA registers

Element Self Description register (ESD) [23:16] is R/WO,so let
write the ESD.CID when we start ich7_setup_root_complex_topology
This value is also used to programme the R/WO 'Target Component ID'
registers of RPxD and HHD.
Once is done, no need to rewrite on them as they become RO(or reserved).
(For more information, please see ICH7 datasheet page 271).
