PM: domains: Allocate gpd_timing_data dynamically based on governor
If a genpd doesn't have an associated governor assigned, there's really no point to allocate the per device gpd_timing_data, as the data isn't being used by a governor anyway. To avoid wasting memory, let's therefore convert the corresponding td variable in the struct generic_pm_domain_data into a pointer and manage the allocation of its data dynamically.
