[PATCH] ARM: pxa: tosa: switch to gpio-charger

[Dmitry Eremin-Solenikov]

Switch to simpler gpio-charger module. PDA power requires additional
setup in platform file and is more suited for boards with separate AC
and USB charging inputs. Tosa has a unified input, so it's better suited
for gpio-charger.
