UPSTREAM: 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.
