MIPS: CPS: Select CONFIG_SYS_SUPPORTS_SCHED_SMT for MIPSr6
Prior to MIPSr6 multithreading is only supported if CONFIG_MIPS_MT_SMP is enabled, so CONFIG_MIPS_MT_SMP selects CONFIG_SYS_SUPPORTS_SCHED_SMT. With MIPSr6 the CONFIG_MIPS_CPS SMP implementation always supports multithreading, so have it select CONFIG_SYS_SUPPORTS_SCHED_SMT in order to allow the scheduler to make better informed decisions on multithreaded MIPSr6 systems (for example those using I6400 or I6500 CPUs).
