Subject: [PATCH v6 0/2] Add support for Xilinx Versal CPM5 Root Port

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 additional register bit
  to enable and handle legacy interrupts.

Changes in v6:
- Added of_device_get_match_data to identify CPM version.
- Used enum values to differentiate CPM version.
