```text
PCI primary bus will be determined by looking for ISA node in device tree.
Also for board ge_imp3a primary bus is the second PCI controller detected.
So we add ISA node to ge_imp3a's device tree to fit the new determination.

Adding ISA node to other boards' device tree is not necessary. The situation
that the first bus is primary have already been handled. Please refer to the
following patch:
powerpc/pci: Make sure ISA IO base is not zero
