[PATCH 4/4] intel_reg_dumper: Add more information when dumping single registers

[damien.lespiau at gmail.com (Damien Lespiau)]

From: Damien Lespiau <damien.lespiau at intel.com>

Now that we can dump registers giving a partial name, adding more
information about the dumped registers seems useful.
