lib/coreboot_table: Add Intel FSP version to coreboot table
Add a new LB_TAG_PLATFORM_BLOB_VERSION for FSP version, it would
add Intel FSP version to coreboot table LB_TAG_PLATFORM_BLOB_VERSION
when PLATFORM_USES_FSP2_0 is selected.
Tested=On OCP Delta Lake, with an updated LinuxBoot payload cbmem utility
can see "LB_TAG_PLATFORM_BLOB_VERSION": "2.1-0.0.1.120"
