sb/intel/i82801[ij]x: do not set Chipset Initialization Register (CIR) 5
The specification updates for ICH 9 & 10 require to leave the
register in its default state by reserving all of its bits.
Writing to it does not seem to make a difference anyway since
reading it afterwards does not reflect the write (tested on ICH10).
Therefore we should omit the writes but document this fact in the
code because it is easy to miss from the datasheet alone.
