[ARM] 5037/1: Orion: fix DNS323/Kurobox Pro PCI initialisation
Whereas most Orion 5x machine support code would initialise the PCI subsystem with nr_controllers in their struct hw_pci set to 2, the DNS323 and Kurobox Pro machine support code had nr_controllers set to 1. This was presumably done because on those two machines, the PCI(-X) controller (nr == 1) isn't used, requiring initialisation of only the PCIe controller (nr == 0.) However, not initialising the PCI(-X) controller on boards that don't use it leads to a situation where both the PCIe and the PCI(-X) controller think that their root bus is zero, and it messes up IRQ assignment. This patch changes the DNS323 and Kurobox Pro support code to always use nr_controllers == 2.
