[arm tegra odm] battery: new driver for whistler

Implementing new dummy odm battery driver for whistler. It is based on
the stub driver and returns success from all the relevant APIs to
prevent failure of probe of tegra-battery driver. If there is no
battery driver then MSD cannot be turned on.

Bug: 715515
