The driver currently uses a global pointer (ltc2952_data) to store its
entire state structure just to access the gpio_kill descriptor during
the power-off sequence.

Refactor the driver to use a specific static gpio_desc pointer for
the kill signal. This addresses the existing TODO in the function.
