[PATCH v6 1/2] iio: frequency: ad9832: remove kernel.h proxy header

[Joshua Crofts <joshua.crofts1@gmail.com>]

Remove kernel.h proxy header and add replacement headers (array_size,
dev_printk.h, kstrtox, mod_devicetable, mutex, types, asm/byteorder) to
maintain atomicity. Moved asm/div64.h header below generic <linux/*>
headers. Additionally, add bitops.h for BIT_ULL() macro.

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