[PATCH v3] iio: frequency: ad9834: clean up includes

[Joshua Crofts]

Cleanup include headers by removing proxy kernel.h header and
unnecessary list.h, interrupt.h, workqueue.h and slab.h headers. Added
additional headers that were previously included from kernel.h.

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