gpio: Don't fiddle with irqchips marked as immutable
In order to move away from gpiolib messing with the internals of
unsuspecting irqchips, add a flag by which irqchips advertise
that they are not to be messed with, and do solemnly swear that
they correctly call into the gpiolib helpers when required.
Also nudge the users into converting their drivers to the
new model.
