in current impl. condition

build_madt() {
  ...
  if (test_bit(i, cpuinfo->found_cpus))

is always true since loop handles only present CPUs
in range [0..smp_cpus).
But to fill usless cpuinfo->found_cpus we do unnecessary
scan over QOM tree to find the same CPUs.
So mark GICC as present always and drop not needed
code that fills cpuinfo->found_cpus.
