We also change the way of determining primary bus for fitting platform

Now we registered pci controllers as platform devices. So we combine =

initialization code as one platform driver.

Changes for V6:
- Fix "isa_io_base could not be zero" bug. Thanks to Ben.

- Determining primary by looking for ISA node does not work for =
ge_imp3a.
It's fixed by adding ISA node to its devied tree.

Why are we adding an isa node to the ge_imp3a.dts?
If this is really needed it should be a separate patch as well.
