No need for pr_err here, the pr_err message in ttm_bo_evict is enough
to draw attention to something not going as planned.

We need to set the NO_EVICT flag on the ghost object or otherwise we are
adding it to the LRU.

When it is added to the LRU we can run into a race between destroying
and evicting it again.

New features for 4.21:
amdgpu:
- Support for SDMA paging queue on vega
- Put compute EOP buffers into vram for better performance
- Share more code with amdkfd
- Support for scanout with DCC on gfx9
- Initial kerneldoc for DC
- Updated SMU firmware support for gfx8 chips
- Rework CSA handling for eventual support for preemption
- XGMI PSP support
- Clean up RLC handling
- Enable GPU reset by default on VI, SOC15 dGPUs
- Ring and IB test cleanups

amdkfd:
- Share more code with amdgpu

ttm:
- Move global init out of the drivers

scheduler:
- Track if schedulers are ready for work
- Timeout/fault handling changes to facilitate GPU recovery

ttm_bo_glob and ttm_mem_glob are defined as structure instance, while
not allocated by kzalloc, so kfree should not be invoked to release

This allows removing all the device code to initialize it.

As the name says we only need one global instance of ttm_bo_global.

Just use a single exported instance which is save to initialize multiple times.

As the name says we only need one global instance of ttm_mem_global.

Drop all the driver initialization and just use a single exported
instance which is initialized during BO global initialization.
