lib: Fix FMAP cache on FSP1.0 platforms

On FSP1.0 platforms CAR region is torn down by FspMemoryInit() on exit,
since there is no FspTempRamExit() API. Current FMAP cache code correctly
assumes CAR is around and usable after. However this assumption is only
correct for >= FSP1.0.

This change address the problem by using cache only if CAR region is
usable.

TEST=boot test on OCP monolake.
