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.
