Kvstore tests api change to run on K64F only

Change KVStore API tests to run only on K64F, these tests check the KVStore functionality without actually testing the board's storage,
Thus they should produce the same results for each device they run on.
K64F was selected for no special technical reason but only because of it being available and convenient to use.
