gpiolib: move gpiolib-sysfs function declarations into their own header Move gpiolib-sysfs function declarations into their own header. These functions are in gpiolib-sysfs.c, and are only required by gpiolib.c, and so should be in a module header, not gpiolib.h. This brings gpiolib-sysfs into line with gpiolib-cdev, and is another step towards removing the sysfs inferface.

gpiolib: Clean up headers There is a few things done: - include only the headers we are direct user of - when pointer is in use, provide a forward declaration - add missing headers - group generic headers and subsystem headers - sort each group alphabetically While at it, fix some awkward indentations.

gpio: sysfs: fix forward declaration of struct gpio_device The forward declaration for struct gpio_device should be provided for both branches of the #ifdef.
