[Intel-gfx] [PATCH 2/4] Use the existing deviceID -> name mapping in SymTabRec instead of duping it.

[Eric Anholt]

We need to have this array anyway for the xf86 interfaces, apparently,
so just store the name in one location.  This drops the i852/i855
subdevice distinction in the name printed, but I haven't seen us ever
care about that.
