[PATCH 11/11] iio: adc: ad7192: Improve include relevance

[Jonathan Cameron <jic23@kernel.org>]

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

Drop unused:
  #include <linux/iio/buffer.h>  // lines 29-29
  #include <linux/iio/trigger.h>  // lines 30-30
  #include <linux/iio/trigger_consumer.h>  // lines 31-31
  #include <linux/iio/triggered_buffer.h>  // lines 32-32
  #include <linux/sched.h>  // lines 20-20
  #include <linux/slab.h>  // lines 15-15

Replace kernel.h with more specific headers and add missing headers.

Justification from iwyu for added headers:
  #include <linux/array_size.h>          // for ARRAY_SIZE
  #include <linux/bitmap.h>              // for for_each_set_bit
  #include <linux/bits.h>                // for BIT, GENMASK
  #include <linux/compiler.h>            // for inline
  #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, DIV_ROU...
  #include <linux/math64.h>              // for do_div
  #include <linux/minmax.h>              // for in_range
  #include <linux/mutex.h>               // for class_mutex_constructor
  #include <linux/stddef.h>              // for true, NULL, false
  #include <linux/types.h>               // for bool, u32, u8, ssize_t
