Use the device lifecycle managed register function. This helps prevent
mistakes like unregistering out of order in cleanup functions and
forgetting to unregister on error paths.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

twl4030_madc_bat_ext_changed() is a wrapper around
"power_supply_changed(psy);" and it has the same prototype.
Remove it, replacing it with making the external_power_changed
callback directly point to power_supply_changed.

Avoid inclusion of unused twl4030-madc.h. This
will allow twl4030-madc.h to be merged into the
iio driver.

This moves all power supply drivers from drivers/power/
to drivers/power/supply/. The intention is a cleaner
source tree, since drivers/power/ also contains frameworks
unrelated to power supply, like adaptive voltage scaling.
