ichspi.c: do not print PBR[3] for ICH7 because it does not exist

Intel document 307013 (ICH7 datasheet) section 21.1.9 does only
define PBR[0] (at SPIBAR + 60h) to PBR[2] (SPIBAR + 68h). SPIBAR + 6Ch
and following are not defined, but we were printing them as PBR[3]
anyway. i could not find any references to PBR[3] in documentation of
other related chips (NM10, atom e6xx) either, hence kill it.
