Input: wm97xx - make missing platform data non-fatal

Browse Source 
Commit 6480af4915 ("power_supply: wm97xx_battery: use
power_supply_get_drvdata") made wm97xx platform data mandatory, although
it's still optional.

This patch fixes an oops during driver probe on one of my MIPS boards with
a wm9712.
