This makes the driver use the data pointer added to the gpio_chip
to store a pointer to the state container instead of relying on
container_of().

These new helpers simplify implementing multi-driver modules and
properly handle failure to register one driver by unregistering all
previously registered drivers.

A pending cleanup will mean that module.h won't be implicitly
everywhere anymore. Make sure the modular drivers in gpio
are actually calling out for <module.h> explicitly in advance.

GPIO drivers are getting consolidated into drivers/gpio. While at it,
change the driver name to mpc5200-gpio* to avoid collisions.
