Most likely those are remanescent from times when we didn't have
gpiolib. It's not long ago (about 2 years) that David Brownell (rip, my
friend) introduced it to the kernel. So those should be converted to
gpiolib and moved to drivers/gpio/ but it doesn't mean we don't need
that piece of code.

With different register layout, register offsets, register sizes, etc,
it would be way uglier to combine all those into one big hacky driver.
