[PATCH] gpio: sysfs: constify gpio class

[Bartosz Golaszewski <brgl@bgdev.pl>]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

All class functions used here take a const pointer to the class
structure. We can constify gpio_class.

While at it: remove a stray newline and use a tab in the struct
definition for consistency with the line above.
