Subject: GPIO update to allow code to get at gpio_chip

Allowing gpiolib implementations to get at the gpio_chip from the
gpio number is useful to allow gpiolib gpio numbering to be used
for other gpio purposes such as changing pin configuration.

The following patch exports this information. A patch showing the
reason for my wanting this can be supplied on request.
