[PATCH 10/12] drm/i915: Clean up intel_get_dram_info() a bit

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Remove the pointless zero initialization of bunch of things
(the thing is kzalloc()ed).

Also throw out the mostly useless on-stack string. I think
it'll be clear enough from the logs that 0 means unknown.
