[git pull] amdkfd next 4.19

[Oded Gabbay]

Hi Dave,

This is amdkfd pull for 4.19. The major changes are:

- Add Raven support. Raven refers to Ryzen APUs with integrated GFXv9 GPU.
- Integrate GPU reset support

In addition, there are a couple of small fixes and improvements, such as:

- Better handling and reporting to user of VM faults
- Fix race upon context restore
- Allow the user to use specific Compute Units
- Basic power management

Thanks,
Oded
