[PATCH 07/11] iio: adc: ad4130: Improve include relevance

[Jonathan Cameron <jic23@kernel.org>]

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

Replace asm/div64.h with linux/math64.h and drop kernel.h in
favor of more specific includes.  Also add some others that should
be directly included to follow approximate include what you use.

Justification for new headers from iwyu with a couple of comments where
this deviates from recommendations.

  #include <linux/array_size.h>      // for ARRAY_SIZE
  #include <linux/bitmap.h>          // for for_each_set_bit
  #include <linux/build_bug.h>       // for static_assert
  #include <linux/compiler.h>        // for __aligned
  #include <linux/completion.h>      // for complete, init_completion, rei...
  #include <linux/container_of.h>    // for container_of

  #include <linux/init.h>            // for THIS_MODULE
Ignored this one as seems reasonable to assume module.h will always include
whereever that is!

  #include <linux/jiffies.h>         // for msecs_to_jiffies
  #include <linux/math.h>            // for rounddown
  #include <linux/math64.h>          // for div_u64, div_u64_rem, DIV64_U6...
  #include <linux/minmax.h>          // for __cmp_op_max
  #include <linux/mod_devicetable.h> // for of_device_id
  #include <linux/mutex.h>           // for class_mutex_constructor, class...
  #include <linux/of.h>              // for of_property_read_string, devic...
  #include <linux/stddef.h>          // for false, true, NULL
  #include <linux/string.h>          // for memcpy, memset
  #include <linux/stringify.h>       // for __stringify
  #include <linux/sysfs.h>           // for sysfs_emit
  #include <linux/types.h>           // for u32, bool, u64, u8, ssize_t

  struct fwnode_handle;
Ignored this last recomendation because I think property.h can reasonably
be expected to always include whereever this is.
