powerpc/shared: ISA bus bridge fails to enable the openpic irq
- The call to enable the openpic irq for the ISA bridge fails
because the IRQ used is offset by the ISA bus signals and
the openpic call expects an IRQ relative to its signals.
- Add the MVME 2600/2700 to the list of boards with an ISA bridge.
Closes #4231
