Subject: [PATCH v2] gpio: palmas: Allow building as a module

From: Aaron Kling <webgeek1234@...il.com>

The driver works fine as a module, so allowing building as such. This
drops the driver specific init in favor of the module macro which does
the same, plus handling exit.

Signed-off-by: Aaron Kling <webgeek1234@...il.com>

Changes in v2:
- Drop module alias and add module device table
- Link to v1: https://lore.kernel.org/r/20250522-gpio-palmas-gpio-v1-1-d6b1a3776ef5@gmail.com
