[PATCH] iio: adc: spear_adc: cleans up and sorts the existing includes

[Rodrigo Gobbi <rodrigo.gobbi.7@gmail.com>]

Remove unused includes and sort the remaining ones.

Signed-off-by: Rodrigo Gobbi <rodrigo.gobbi.7@gmail.com>
---
At [1] it was suggested to sort and remove some unused includes,
that is the reason for this patch. Removed the following includes
due not being used or because some of them, like device.h/kernel.h
are included indirectly from another .h file. What was removed:

#include <linux/device.h>
#include <linux/kernel.h>
#include <linux/slab.h>
#include <linux/err.h>
#include <linux/iio/sysfs.h>

Also ordered them alphabetically as other adc/iio drivers.
Tks and regards.
