configs: Drop reference to USE_CANNONLAKE_FSP_CAR

This follows commit 5e8c906 which removed the symbol. Since Kconfig
is going to become more strict about unknown symbols, fix it.

As the config file's name indicates that its sole purpose is to test
integration of FSP's CAR, just drop the configuration altogether.
