[PATCH 17/23] gpio: mockup: rename and move around debugfs callbacks

[Bartosz Golaszewski <brgl@xxxxxxxx>]

From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

We will soon introduce new debugfs attributes for dynamically created
chips. We'll reuse the gpio_mockup_debugfs_open() helper for them but
the relevant write callbacks will of course be different.

Let's rename gpio_mockup_debugfs_write() to
gpio_mockup_debugfs_pull_write() to avoid confusion with new write
callbacks and move gpio_mockup_debugfs_open() higher up in the code to
separate it from the pull/value attribute which will no longer be the
only user.
