Set default package to build for POWER10

Set default package to build for p10 (since that is latest code)
Add PLDM as requirement for building p10
Default build will not enable PHAL support by default because of current
build limitations of the PHAL code.

The pldm Interface class will no longer be created in the Manager object
constructor to prevent issues with unit test.

Tested on Rainier

OpenPOWER OCC Control Service

This service will handle communications to the On-Chip Controller (OCC) on Power processors. The OCC provides processor and memory temperatures, power readings, power cap support, system power mode support, and idle power saver support. OCC Control will be interfacing with the OCC to collect the temperatures and power readings, updating the system power mode, setting power caps, and idle power save parameters.

The service is started automatically when the BMC is started.

Build Project

This project can be built with meson. The typical meson workflow is: meson builddir && ninja -C builddir.

Server

The server will start automatically after BMC is powered on.

Server status: systemctl status org.open_power.OCC.Control.service

To restart the service: systemctl restart org.open_power.OCC.Control.service

Configuration

Service files are located in service_files subdirectory.
