power_supply: Mark twl4030_charger as broken

The driver is not buildable without MFD changes. For now, let's
disable the driver as it breaks build for major platforms (i.e. x86).

  CC [M]  drivers/power/twl4030_charger.o

make[2]: *** [drivers/power/twl4030_charger.o] Error 1

We can re-enable it if MFD tree will finally merge into 2.6.37.
