Drop linux/iio/sysfs.h since it is unused and replace linux/kernel.h
with more explicit headers. There are a couple of other headers added
weren't covered by kernel.h, like linux/gpio/consumer.h that are added
since the module makes used of those APIs as well.

bitops.h is implied by bitmap.h, but I'm fine with this being left untouched.
