15f9feb564 drm/tegra: Remove PM from virtual engine 
Remove power management functionality from virtual engine driver
as it's no longer needed. This includes suspend/resume operations
and PM ops structure. The driver now relies on system's default
power management behavior.

db0d9da92f drm/tegra: Fix Engine timestamp shift factor 
In Orin and previous chipsets, engine timestamp counter
runs 32 times faster than CNTVCT register, so the actual
timestamp is obtained by right shifting with factor of 5.
In Thor onwards, this shift is not required is for VIC engine.
