Juri Lelli bf5015a50f sched/topology: Clarify root domain(s) debug string
When scheduler debug is enabled, building scheduling domains outputs
information about how the domains are laid out and to which root domain
each CPU (or sets of CPUs) belongs, e.g.:

 CPU0 attaching sched-domain(s):
  domain-0: span=0-5 level=MC
   groups: 0:{ span=0 }, 1:{ span=1 }, 2:{ span=2 }, 3:{ span=3 }, 4:{ span=4 }, 5:{ span=5 }
 CPU1 attaching sched-domain(s):
  domain-0: span=0-5 level=MC
   groups: 1:{ span=1 }, 2:{ span=2 }, 3:{ span=3 }, 4:{ span=4 }, 5:{ span=5 }, 0:{ span=0 }

 [...]

 span: 0-5 (max cpu_capacity = 1024)

The fact that latest line refers to CPUs 0-5 root domain doesn't however look
immediately obvious to me: one might wonder why span 0-5 is reported "again".

Make it more clear by adding "root domain" to it, as to end with the
following:

 CPU0 attaching sched-domain(s):
  domain-0: span=0-5 level=MC
   groups: 0:{ span=0 }, 1:{ span=1 }, 2:{ span=2 }, 3:{ span=3 }, 4:{ span=4 }, 5:{ span=5 }
 CPU1 attaching sched-domain(s):
  domain-0: span=0-5 level=MC
   groups: 1:{ span=1 }, 2:{ span=2 }, 3:{ span=3 }, 4:{ span=4 }, 5:{ span=5 }, 0:{ span=0 }

 [...]

 root domain span: 0-5 (max cpu_capacity = 1024)
