[MACHINE][C72] Add different machine config for Nano and Nano Lite CPU
Nano Lite SoC lacks the integrated GPU. Some packages are compiled with specific flags when graphics acceleration is not available. In this case, Weston needs to be compiled with specific flags to work without GPU. Unfortunately, meta-freescale layer lacks the specific MACHINEOVERRIDE_EXTENDER for I.MX8M Nano Lite SoC, so we need to define it.
