Add suspend, resume and rail_off_ready API into tegra_cpu_car_ops. These functions were used for CPU powered-down state maintenance.

Perhaps simplify that to: return cpu_rst_status & 2; or perhaps if that generates an int->bool performance warning: return !!(cpu_rst_status & 2); or: return (cpu_rst_status >> 1) & 1;
