meta-ampere: Add Mt.Jade machine

Add initial Mt.Jade platform support with minimal configuration so that
the code can be compiled and booted on the Mt.Jade platform system.

Tested:
 1. Compile OpenBMC image for Mt.Jade successfully and can boot on
Mt.Jade.
 2. Login to console and WebUI successfully.
