[PATCH 1/4] iio: magnetometer: ak8975: header cleanup

[Joshua Crofts]

Clean up headers by removing proxy kernel.h header and adding new
headers to ensure atomicity (array_size.h, dev_printk.h, types.h,
asm/byteorder.h). Removed unused headers (slab.h, iio/sysfs.h,
iio/trigger.h) and added minmax.h, property.h, wait.h, irqreturn.h to
mitigate transient dependencies during compilation.

Audited using the include-what-you-use tool.
