[PATCH v2] iio: accel: stk8ba50: Update includes to match IWYU

[Miao Li]

From: Miao Li <limiao@xxxxxxxxxx>

Update the list of included headers in stk8ba50.c using
Include-What-You-Use (IWYU) tool, mainly to remove kernel.h
and add missing headers such as array_size.h, bits.h,
dev_printk.h, etc.

Changes in v2:
- Drop linux/iio/types.h as it is already included by linux/iio/iio.h
- Link to v1: 
  https://lore.kernel.org/all/20260603015033.187735-1-limiao870622@xxxxxxx/
