PCI: dwc: Combine iATU detection procedures

Since the iATU CSR region is now retrieved in the DW PCIe resources getter
there is no much benefits in the iATU detection procedures splitting up.
Therefore let's join the iATU unroll/viewport detection procedure with the
rest of the iATU parameters detection code. The resultant method will be
as coherent as before, while the redundant functions will be eliminated
thus producing more readable code.
