Add a void *data pointer to struct generic_pm_domain_data. Because this
exists for each device associated with a genpd it will allow us to
assign per-device data if needed on a platform for control of that

This will allow greater flexibility for genpd providers to use their own
arguments that are passed in the phandle and interpret them however they
see fit.
