Unbinding amdgpu has no problems, but binding it again leads to an
error of sysfs file already existing. This is because it wasn't
actually cleaned up on unbind. Add the missing cleanup step.

amdgpu_acpi_detect() calls some helper functions it calls have large
local structures. When the compiler inlines these helpers, their local
data adds to the amdgpu_acpi_detect() stack frame.
Mark the helpers with noinline_for_stack:
- amdgpu_atif_verify_interface()
- amdgpu_atif_get_notification_params()
- amdgpu_atif_query_backlight_caps()
- amdgpu_atcs_verify_interface()
- amdgpu_acpi_enumerate_xcc()
This keeps the large temporary objects inside the helper’s own stack
frame instead of being inlined into the caller, preventing the caller
from growing beyond the stack limit.
Fixes the below with gcc W=1:
drivers/gpu/drm/amd/amdgpu/amdgpu_acpi.c:1403:6: warning: stack frame size (1688) exceeds limit (1024) in 'amdgpu_acpi_detect' [-Wframe-larger-than]

drm_sched_job_add_resv_dependencies can fail in amdgpu_ttm_prepare_job.

No functional change for now, but this struct will have more
fields added in the next commit.
This change would introduce synchronisation issue, because
dependencies between successive jobs are not taken care of
properly. For instance, amdgpu_ttm_clear_buffer uses
amdgpu_ttm_map_buffer then amdgpu_ttm_fill_mem which should
use different entities (default_entity then move/clear entity).
To prevent failures for this commit, we limit ourselves to
2 entities: default_entity (which replaces high_pr usages) and
clear_entity (which replaces low_pr usages).
The next commits will deal with these dependencies correctly,
and then we'll be able to use move_entity.

v2: renamed amdgpu_ttm_buffer_entity
v4: don't use move_entity in ttm yet
