google/lars: perform early init for CAR *stage
In order to support both separate verstage and a verified boot after
romstage one needs to ensure the proper GPIO and EC configuration
been complete. Therefore, move that logic to
car_mainboard_post_console_init() in car.c file which gets called
in the early flow of a CAR stage (either verstage or romstage).
