topology: Introduce cpu_smt_mask for CONFIG_SCHED_SMT=n
Define cpu_smt_mask in case of CONFIG_SCHED_SMT=n as cpumask_of that
CPU. With that config, it is expected that kernel treats each CPU
as individual core. Using cpumask_of(cpu) reflects that.
This would help to get rid of the ifdeffery that is spread across
the codebase since cpu_smt_mask is defined only in case of
CONFIG_SCHED_SMT=y.
Note: There is no arch today which defines cpu_smt_mask unconditionally.
So likely defining the cpu_smt_mask shouldn't lead redefinition errors.
