Support the PMD power management API in MLX5 driver.
The monitor policy of this API puts a CPU core to sleep until
a data in some monitored memory address is changed by the NIC.
Implement the get_monitor_addr function to return an address
of a CQE owner bit to monitor the arrival of a new packet.

Hi David, Anatoly,

What to you think adding "Power Monitoring" as a new feature in the NIC feature
table? So the drivers supporting it can advertise it.
https://doc.dpdk.org/guides/nics/overview.html

For it need to,
- add "Power Monitoring" to template .ini file,
'.doc/guides/nics/features/default.ini'
- Document it in the features file, '.doc/guides/nics/features.rst'
- Update driver .ini files to advertise the feature, like 'ixgbe.ini'
