Hou Zhiqiang 8bcca26585 PCI: dwc: Move iATU detection earlier ...

dw_pcie_ep_init() depends on the detected iATU region numbers to allocate
the in/outbound window management bitmap.  It fails after 281f1f99cf
("PCI: dwc: Detect number of iATU windows").

Move the iATU region detection into a new function, move the detection to
the very beginning of dw_pcie_host_init() and dw_pcie_ep_init().  Also
remove it from the dw_pcie_setup(), since it's more like a software
initialization step than hardware setup.
