88pm860x_battery and charger: Fix a few post-merge issues

Sparse complains:

drivers/mfd/88pm860x-core.c:803:53:    got struct regulator_bulk_data static [toplevel] *

The issues are minor, except for the last one. We seemed to use
'regulator_bulk_data' struct (just as charger manager documentation
wrongly tells us), but in real it should have been
'struct charger_regulator'. The only reason that it worked is
because both 'supply' and 'regulator_name' struct members are the
first in these structs. :-)
