Dear Henry,

I just modify the code that related to SKU ID, eventually, I confirmed with our EE, foob cooreboot section leverage to phaser is fine.
So:
1. devicetree need not modificatoin
2. default GPIO setting is fine
3. remove mainboard.c and variant.c, which related to SKU IDs.

Thanks and best regards
