Return value of 'to_amdgpu_crtc' which is container_of(...) can't be
null, so it's null check 'acrtc' is dropped.

Fixing the below:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:9302 amdgpu_dm_atomic_commit_tail() error: we previously assumed 'acrtc' could be null (see line 9299)

Added 'new_crtc_state' NULL check for function
'drm_atomic_get_new_crtc_state' that retrieves the new state for a CRTC,
while enabling writeback requests.

A static checker pointed out, that bo_va->base.bo was already derefenced
earlier in the same scope. Therefore this check is unnecessary here.

Calling amdgpu_device_ip_resume_phase1() during shutdown leaves the
HW in an active state and is an unbalanced use of the IP callbacks.

Using the IP callbacks like this can lead to memory leaks, double
free and imbalanced reference counters.

Leaving the HW in an active state can lead to DMA accesses to memory now
freed by the driver.

Both is a complete no-go for driver unload so completely revert the
workaround for now.

This reverts commit f5c7e779.

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().

Note that the upper limit of ida_simple_get() is exclusive, but the one of
ida_alloc_range() is inclusive. So a -1 has been added when needed.

It is likely that the statement related to 'dml_edp' is misplaced. So move
