[PATCH 05/11] iio: adc: max11100: Improve include relevance

[Jonathan Cameron <jic23@kernel.org>]

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

Using the iwyu tool to help, drop kernel.h in favor of more specific
headers.
Also drop a delay.h and iio/driver.h as neither was used.
Add other headers that were relying on indirect includes.

Justification for additions:
  #include <linux/array_size.h>      // for ARRAY_SIZE
  #include <linux/bits.h>            // for BIT
  #include <linux/compiler.h>        // for __aligned
  #include <linux/dev_printk.h>      // for dev_err
  #include <linux/device/devres.h>   // for devm_add_action_or_reset
  #include <linux/err.h>             // for EINVAL, IS_ERR, PTR_ERR, ENOMEM
  #include <linux/minmax.h>          // for __cmp_op_max
  #include <linux/types.h>           // for u8
