[PATCH v5 1/7] platform/surface: gpe: use platform_device_register_full()

[Bartosz Golaszewski <bartosz.golaszewski@oss.qualcomm.com>]

Creating a software node for a given set of properties and adding it to
a platform device can be achieved with a single call to
platform_device_register_full(). There's nothing in this driver that
suggests using the more fine-grained interfaces was intentional so
switch to using the high-level helper.
