ec66841e49 viafb: move some include files to include/linux
These are the files which should be available to subdevices compiled
outside of drivers/video/via.

9221fc6556 viafb: Eliminate some global.h references
The various subdev drivers (other than the framebuffer itself) no longer
need this file.

27fe971d08 viafb: Do not remove gpiochip under spinlock
gpiochip_remove() is not meant to be called with interrupts disabled, and
there is no need for the lock here in any case.

7e0de02268 viafb: add a driver for GPIO lines
This is a simple gpiolib driver giving access to the GPIO lines in the
VIA framebuffer system.  A simple mechanism exists for switching lines
between GPIO and I2C, but it's only compile-time for now.
