[PATCH 0/2][SRU][OEM-OSP1-B] CPU package state stuck at PC3 with nvidia dGPU in power saving mode

[AceLan Kao]

BugLibk: https://bugs.launchpad.net/bugs/1864606

[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.
