mb/google/cherry: Initialize PCIe by SKU encoding
All cherry boards (tomato, dojo) share the same SKU ID encoding, in the sense that a device has NVMe storage if and only if the BIT(1) of SKU ID is set (otherwise eMMC). Therefore, instead of hard coding the list of NVMe (PCIe) SKU IDs, we check the BIT(1) to decide whether to initialize PCIe. In addition, in preparation for UFS devices coming in the future, reserve BIT(3) (which is unset for all of current SKUs) for them.
