[PATCH 3/8] spapr: Clean up local variable shadowing in spapr_dt_cpus()

[Cédric Le Goater]

Introduce a helper routine defining one CPU device node to fix this
warning :

  ../hw/ppc/spapr.c: In function ‘spapr_dt_cpus’:
  ../hw/ppc/spapr.c:812:19: warning: declaration of ‘cs’ shadows a previous 
local [-Wshadow=compatible-local]
    812 |         CPUState *cs = rev[i];
        |                   ^~
  ../hw/ppc/spapr.c:786:15: note: shadowed declaration is here
    786 |     CPUState *cs;
        |               ^~
