Nathan Lynch 6e891b0406 powerpc/prom: Add CPU info to hardware description string later 
[ Upstream commit 7bdd1c6c87de758750d419eedab7285b95b66417 ]

cur_cpu_spec->cpu_name is appended to ppc_hw_desc before cur_cpu_spec
has taken on its final value. This is illustrated on pseries by
comparing the CPU name as reported at boot ("POWER8E (raw)") to the
contents of /proc/cpuinfo ("POWER8 (architected)"):

  $ dmesg | grep Hardware
  Hardware name: IBM,8408-E8E POWER8E (raw) 0x4b0201 0xf000004 \
    of:IBM,FW860.50 (SV860_146) hv:phyp pSeries

  $ grep -m 1 ^cpu /proc/cpuinfo
  cpu             : POWER8 (architected), altivec supported

Some 44x models would appear to be affected as well; see
identical_pvr_fixup().

This results in incorrect CPU information in stack dumps --
ppc_hw_desc is an input to dump_stack_set_arch_desc().

Delay gathering the CPU name until after all potential calls to
identify_cpu().
