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.
