i2c: nvidia-gpu: drop empty stub for runtime pm

Browse source 
After the commit c5eb119007 ("PCI / PM: Allow runtime PM without callback
functions") we no more need empty stubs for runtime-pm to work.

The driver has no device specific task(s) for .suspend() . The stub was
placed just for runtime-pm, which can be dropped now.
