The dev_t is defined in types.h while struct gpio_device forward declaration
is missed. Take into account above and update header block in gpiolib-cdev.h.

Make the gpiolib-cdev module a build option. This allows the CDEV
interface to be removed from the kernel to reduce kernel size in
applications where is it not required, and provides the parent for
other CDEV interface specific build options to follow.

Split the cdev specific functionality out of gpiolib.c and into
gpiolib-cdev.c. This improves the readability and maintainability of both
the cdev and core gpiolib code.
