These are the files which should be available to subdevices compiled
outside of drivers/video/via.

The various subdev drivers (other than the framebuffer itself) no longer
need this file.

gpiochip_remove() is not meant to be called with interrupts disabled, and
there is no need for the lock here in any case.

Another step toward making this thing a real multifunction device driver.

Also add low-level locking to the i2c driver.

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.
