At present we assume that CAR (Cache-as-RAM) is used if HOBs (Hand-off bLocks) are not, since HOBs typically indicate that an FSP is in use, and

FSPs handle the CAR init.
However this is a bit indirect, and for FSP2 machines which use their own CAR implementation (such as apollolake) but use the FSP for other functions, the logic is wrong.
To fix this, add a dedicated Kconfig option to indicate when CAR is used.
