Instead of a list of separate busy placement add flags which indicate
that a placement should only be used when there is room or if we need to
evict.

v4: fix some typos pointed out by checkpatch

Issue: during evict or validate happened on amdgpu_bo, the 'from' and
'to' is always same in ftrace event of amdgpu_bo_move

where calling the 'trace_amdgpu_bo_move', the comment says move_notify
is called before move happens, but actually it is called after move
happens, here the new_mem is same as bo->resource

Fix: move trace_amdgpu_bo_move from move_notify to amdgpu_bo_move

This worked by luck if the GART aperture ended up at 0.  When
we ended up moving GART on some chips, the GART aperture ended
up offsetting the AGP address since the resource->start is
a GART offset, not an MC address.  Fix this by moving the AGP
address setup into amdgpu_bo_gpu_offset_no_check().

v2: check mem_type before checking agp
v3: check if the ttm bo has a ttm_tt allocated yet

The default AGP settings were overwriting the IP selected
ones since the default was getting set after the IP ones
were selected.

To disable AGP, the start needs to be set to a higher
value than the end.  Set a default disable value for
the AGP aperture and allow the IP specific GMC code
to enable it selectively be calling amdgpu_gmc_agp_location().
