gpu: nvgpu: add domain name API

Browse Source 
Add nvgpu_nvs_domain_get_name() to minimize messing up with nvs
internals and to help code organization when nvs is not built in yet. A
stub to help compilation returns NULL because no domains can exist when
the stub is built in, and thus it won't be used.
