iio: remove .owner field for driver using module_platform_driver
This patch removes the .owner field for drivers which use the
platform_driver_register api because this is overriden in
_platform_driver_register.

iio: delete non-required instances of include <linux/init.h>
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

iio: adc: twl6030-gpadc: Remove redundant code
The if check is redundant as the value obtained from
iio_device_register() is already in the required format.
Hence return the function directly.

iio: adc: twl6030-gpadc: fix error return code in twl6030_gpadc_read_raw()
Fix to return -EINTR in the error handling case instead
of 0 (ret is assigned after goto, which has no effect),
as done elsewhere in this function.

iio: twl6030-gpadc: TWL6030, TWL6032 GPADC driver
The GPADC is general purpose ADC found on TWL6030, and TWL6032 PMIC,
known also as Phoenix and PhoenixLite.
The TWL6030 and TWL6032 have GPADC with 17 and 19 channels
respectively. Some channels have current source and are used for
measuring voltage drop on resistive load for detecting battery ID
resistance, or measuring voltage drop on NTC resistors for external
temperature measurements. Some channels measure voltage, (i.e. battery
voltage), and have voltage dividers, thus, capable to scale voltage.
Some channels are dedicated for measuring die temperature.
Some channels are calibrated in 2 points, having offsets from ideal
values kept in trim registers. This is used to correct measurements.
The differences between GPADC in TWL6030 and TWL6032:
- 10 bit vs 12 bit ADC;
- 17 vs 19 channels;
- channels have different purpose(i.e. battery voltage
channel 8 vs channel 18);
- trim values are interpreted differently.
Based on the driver patched from Balaji TK, Graeme Gregory, Ambresh K,
Girish S Ghongdemath.
