[PATCH 08/11] iio: adc: ad7124: Improve include relevance

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Drop unused linux/kfifo.h and linux/iio/sysfs.h.
Replace kernel.h with more specific headers and add other missing
headers that should be directly included to follow approximate include
what you use principles.

Justification for new headers from iwyu:
  #include <linux/array_size.h>          // for ARRAY_SIZE
  #include <linux/container_of.h>        // for container_of
  #include <linux/kstrtox.h>             // for kstrtobool
  #include <linux/limits.h>              // for U32_MAX
  #include <linux/math.h>                // for DIV_ROUND_CLOSEST, abs
  #include <linux/mutex.h>               // for class_mutex_constructor
  #include <linux/slab.h>                // for __free_kfree
  #include <linux/stddef.h>              // for true, NULL, false, struct_...
  #include <linux/types.h>               // for bool, u32, u8, size_t, ssi...
