[PATCH] pm: Fix build issues in ds278* (thinkpad_acpi)

[Ognjen Galic <smclt30p@gmail.com>]

This patch fixes a issue introduced by the thinkpad_acpi
and battery patch series for charging thresholds.

In that series, a new macro has been added to
"include/linux/power_supply.h:374" called to_power_supply
which is used to upcast from a struct device to a struct
power_supply. That change conflicts with the private
implementation of to_power_supply inside the ds2780
and ds2781 battery modules.

This patch removes those private implementations and
uses the new header one.

After applying the thinkpad_acpi and battery patch
series this must be applied to fix the build issues.

This patch depends on:

"[PATCH v10 2/4] pm: add to_power_supply macro to the API"
