radeon: add support for DDC on some laptop chipsets
I noticed fglrx has DDC for the panel in the rs480 laptop, however radeon
didn't pick it up, so I valgrinded fglrx and spotted 0x1a0/0x1a4 accesses
I actually noticed this before from the BIOS but never figured it out.
So now I get DDC from the LCD on this laptop.
