This registers custom sysfs properties using the native functionality
of the power-supply framework, which cleans up the code a bit and
fixes a race-condition. Before this patch the sysfs attributes were
not properly registered to udev.

Variable charging_start is being set but is never read, it is therefore
redundant and can be removed. Cleans up sparse warning:
drivers/power/supply/pcf50633-charger.c:61:3: warning: Value stored to
'charging_start' is never read

attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/sysfs.h> work
with const attribute_group. So mark the non-const structs as const.

Simplify return logic to avoid unnecessary variable assignments.
These issues were detected using Coccinelle and the following semantic patch:
@@
local idexpression ret;
expression e;
@@
-ret =
+return
e;
-return ret;

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.
