Match BOM to get HWQual ID, write proper GBB, and do component test.

Match BOM to get HWQual ID, write proper GBB, and do component test.

The HWQual ID is found by matching BOM list.
The GBB file and the qualified component file are selected by HWQual ID.

So the control flow for doing that:
 - Run hardware_Components test with ignored cids, like RO hash, HWQual ID, etc;
 - Obtain the HWQual ID from the above test;
 - Select proper GBB file belonging to the HWQual ID and run factory_WriteGBB;
 - Select proper qualified component file belonging to the HWQaul ID and run
   hardware_Component test.

TEST=manual, run the above flow in a real device.
