Marek Vasut 20874a6072 power-domain: Return 0 if ops unimplemented and remove empty functions
In case the ops is not implemented, return 0 in the core right away.
This is better than having multiple copies of functions which just
return 0 in each power domain driver. Drop all those empty functions.
