Bin Meng b2e02d2865 x86: Add basic support to queensbay platform and crownbay board
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.
