OK that's one way to do it. I wonder if this approach also works for
BCMBCA given Haojian's comments on my previous patch attempts.

drivers/pinctrl/bcm/pinctrl-bcm4908.c would then be phased over
to pinctrl-single, or does the MSB/LSB register layout create a
problem? If we always write 0 into MSB I guess we could just add
some quirk...
