The function twl4030_bci_property_is_writeable can be made static
as it does not need to be in global scope.

We can't assume that the battery is or stays present after probing
on devices with replaceable battery.
On some devices (e.g. GTA04 or OpenPanodra) it can be removed
and even be hot swapped by the user while device continues to operate
through external AC or USB power (as long as system power consumption
remains below ca. 500mA as provided by USB). Under certain conditions
it is possible to boot without battery.
So it makes no sense to check for this situation during probe and make
the charger driver (and its status reports) completely non-operational if
the battery can be inserted later.
Tested on: GTA04 and OpenPandora.

Currently, the twl4030 charger defines its own max_current by directly
creating sysfs nodes. It should use the input_current_limit property
which is e.g. used by the bq24257 driver.
This patch adds the input_current_property with the same semantics as
the max_current property. The code to manage the max_current property
is removed by a separate patch.

Even if bus is not hot-pluggable, the devices can be unbound from the
driver via sysfs, so we should not be using __exit annotations on
remove() methods. The only exception is drivers registered with
platform_driver_probe() which specifically disables sysfs bind/unbind
attributes.

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.
