Implement minimum required functions for the basic support to queensbay platform and crownbay board. Currently the implementation is to call fsp_init() in the car_init(). We may move that call to cpu_init_f() in the future. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
