soc/intel/tigerlake: Enable Hybride storage mode
For using hybrid storage(optane), we need to use 2x2 PCIe configuration while we need to use 1x4 PCIe configuration for NVMe. And this can be configured by fit configuration which is built time. By enabling Hybrid Storage mode in FSP, FSP will detect Hybrid storage and configure PCIe lane accordingly during boot up and save configuration for next boot up.
