Xilinx Versal Premium series has CPM5 block which supports Root Port
functioning at Gen5 speed.

Xilinx Versal CPM5 has few changes with existing CPM block.
- CPM5 has dedicated register space for control and status registers.
- CPM5 legacy interrupt handling needs additonal register bit
  to enable and handle legacy interrupts.

Changes in v5:
- Added of_device_get_match_data to identify CPM version.
