ati-vga: Add some register definitions for debugging

Add names for AMCGPIO regs to make it easier to identify these in trace output. This is where rage128p has the DDC from the DVI port among others but because we don't implement the flat panel controller we don't want to connect an EDID here to make sure drivers use the VGA output instead. But since these are often probed by drivers it helps to see what happens by logging these registers by name.
