drm: add X600 PCI IDs

From: Brice Goglin <[e-mail]>

Now that Xorg 6.9/7.0 has been released, DRI is supported on more Radeon
cards without ATI proprietary drivers. I got my X300 to work without
problem. But, another Radeon X600 required to add its PCI ids to the
Radeon driver. Patch is attached.

I can't be sure about the "CHIP_RV350", I copied it from the X300 entry
(from http://dri.freedesktop.org/wiki/ATIRadeon, X600 is a rv380 chip while
X300 is a rv370). But, at least it works now.
