power: qpnp-fg: Add support for force loading battery data

Currently we support loading battery profile data based on the
best matching profile. If there are 2 battery profiles with the
same battery id, then the profile which is defined first will be
loaded. Provide a module parameter "qpnp_fg.battery_type" so that
the user can force load a battery profile data.
