[PATCH v4 2/6] iio: adc: bcm_iproc_adc: fix include dependencies

[mdshahid03]

From: Mohammad Shahid <mdshahid03@xxxxxxxxx>

Add the headers required directly by the driver for the APIs and
types it uses.

Remove the unused linux/io.h header now that register access is
handled through regmap APIs.
