PCI: dwc: Define maximum number of vectors
Add a callback to define the maximum number of vectors used by the RC. Since this is a parameter associated to each SoC IP setting, makes sense to be configurable and easily visible to future modifications. Set DesignWare driver vectors number maximum to 256.
