Convert the prototype to return and int. This is just an initial step,
needed to support error handling.

This patch is intended as fix for 3.18 rc[n]. Why?

There are other SOC specific patches around that adds genpd support and which
implements the ->attach_dev() callback. To prevent having an "atomic" patch
during the next release cycle, let's change the prototype now instead.

Further patches will add the actual error handling in genpd and these can then
be reviewed and tested thoroughly.
