Bug description:
[Impact]
On a certain Dell laptop which comes with nvidia dGPU, the CPU package state
stuck at PC3 in power saving mode(uses iGPU)
[Fix]
It requires below commit(from v5.3-rc1) for runtime pm to work, and to avoid
conflict, have to introduce another refactor commit.
d4a4f927e4dd i2c: nvidia-gpu: add runtime pm support
cb7302fbe365 i2c: nvidia-gpu: refactor master_xfer
[Test]
Verified on the target laptop, it enters PC10 during long idle.
[Regression Potential]
Low, the commit simply adds runtime pm support.
