Subject: [PATCH 67/84] lscpu: Fix model and model name on Power Systems

On Power System, lspcu presently displays system model number instead of
processor model name. 'model' tag in cpuinfo contains system model name,
not processor model. Instead it uses 'cpu' tag for processor model name.
Also it uses 'revision' tag for processor model.

Fix lspcu so that it displays processor model number. Also display processor
model name.

cpuinfo output on Power System:
  ...
  ...

  processor	: 127
  cpu		: POWER8E (raw), altivec supported
  clock		: 4322.000000MHz
