[PATCH v5 1/2] platform/x86: samsung-galaxybook: Refactor camera lens cover input device

[Ayaan Mirza Baig <ayaanmirzabaig85@gmail.com>]

Rename the camera_lens_cover_switch input device to a generic input
device which can be used for multiple input events. Move input device
allocation and registration into a dedicated galaxybook_input_init()
helper which is called early in probe so that the device is available
to all features.

No functional change.
