Do not use OCP85XX_LBC_OFF twice when accessing LBC registers on MPC85XX.
It turns LBC control registers were not programmed correctly on MPC85XX. We
were accessing bogus addresses as the base offset (OCP85XX_LBC_OFF) was
erroneously added during offset calculations. Effectively the state of LBC
control registers was not altered by the kernel initialization code, but
everything worked as long as we coincided to use the same settings (LBC decode
windows) as firmware has initialized.
