The pcireg base is not assigned to any address, reading the
pcireg base with PS_LINKUP_OFFSET which is incorrect and
giving random values. So update the pcireg base from
devicetree so that we can read the valid PCIE link status
and PHY ready status.

This patch adds the PCIe controller driver for the Xilinx / AMD ZynqMP
NWL PCIe Bridge as root port. The driver source is partly copied from
the Linux PCI driver and modified to enable usage in U-Boot (e.g.
simplified and interrupt support removed).
