[PATCH v2] iio: accel: stk8312: Update includes to match IWYU

[Miao Li]

From: Miao Li <limiao@xxxxxxxxxx>

Update the list of included headers in stk8312.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.

Meanwhile, sort these headers in alphabetical order.
