of/pci: Remove unused MSI controller helpers
All users of the small MSI controller API have been migrated to use the generic MSI infrastructure instead. We no longer need a global chained list of msi_controller. Instead, MSI controllers are now represented as IRQ domains attached to OF nodes, and the resolution between a device requesting an MSI and the corresponding MSI controller is done by the generic interrupt resolution logic. Therefore, this API is now completely useless, and can be removed from the kernel.
