Introduce zynqmp specific defines for the firmware calls.
See EEMI:
https://www.xilinx.com/support/documentation/user_guides/ug1200-eemi-api.pdf
The error codes are described, under XIlPM Error Codes:
https://www.xilinx.com/support/documentation/user_guides/ug1137-zynq-ultrascale-mpsoc-swdev.pdf
- pm_api_id
These are the EEMI function IDs. Unavoidable.
- pm_ret_status
These are the EEMI return statuses. Unavoidable.
