power_supply: wm97xx_battery: use power_supply_get_drvdata

Browse Source 
As the power supply framework provides a way to store and retrieve
private supply data, use it.

In the process, change the platform data for wm97xx_battery from a
container of a single struct wm97xx_batt_pdata to the direct point to wm97xx_batt_pdata.
