PCI: xilinx-cpm: Add support for Versal CPM5 Root Port
The Xilinx Versal Premium series has CPM5 block which supports Root Port
functioning at Gen5 speed.
Xilinx Versal CPM5 has a few changes from the existing CPM block:
- CPM5 has dedicated register space for control and status registers.
- CPM5 legacy interrupt handling needs additional register bit to enable
and handle legacy interrupts.
Add support for the new CPM5 features.
[bhelgaas: compare variant->version with CPM5 explicitly]
