We can't really merge it with vchiq_queue_message() as it has internal

The chip is hardwired to the board's PCIe bus and needs to be properly
setup trough a firmware routine after a PCI fundamental reset. Pass the
reset controller phandle that takes care of triggering the
initialization to the relevant PCI device.

The idea behind this was to create an opaque handle to struct
