If either twl4030_charger or twl4030_madc is configured as MODULE,
we get build (link) errors.
To solve, the direct call of twl4030_get_madc_conversion() is replaced
by a call to iio_read_channel_processed().

This patch adds support for the tps65217 charger driver. This driver is
responsible for controlling the charger aspect of the tps65217 mfd.
Currently, this mainly consists of turning on and off the charger, but
some other features of the charger can be supported through this driver.

Use managed resource function devm_power_supply_register instead
of power_supply_register to simplify the error path by allowing
unregister to happen automatically on error. To be compatible with
the change, replace various gotos by direct returns and remove
unneeded label err.
Also, remove max8998_battery_remove as it is now redundant.

By accident I stumbled over a few misspelled words in the
charger-manager header file which this patch fixes. Namely:
- Extcon rather than Exton
- constraint rather than constratint
- existence rather than existance
- difference rather than diffential
While at it also add a missing space before a closing comment star
forward-slash.
