Nitin Kumbhar 97c6a10928 gpu: nvgpu: add pm_rumtime fixes 
Runtime PM is enabled only for iGPU and not for dGPU. For dGPU,
the .probe() of driver pm_runtime_disable()s, if rail-gating is
not enabled. With nvgpu kernel module load/unload, .probe() is
called multiple times for same struct device *. This results
in an overflow of disable_depth (3 bit refcount) and enables
runtime PM on 8th iteration and calls RTPM routines even if it's
disabled.

To effectively manage pm_runtime_disable(), move it from common
nvgpu_remove() to iGPU/dGPU specific routines.

Also, add restore pm_runtime state of device on driver .remove().

Bug 1987855
