Add battery modules to initfs for some sdm660-based devices

Having battery charger and fuelgauge modules in initfs will allow device battery to be charged e.g. in debug-shell mode, instead of slowly discharging and dying.

This also fixes asus-x00td; it already had some battery modules init modules-initfs, but rradc was forgotten, and it is a required dependency for charger.
