8cdbad98c5 drm/amd/powerplay: Followup fixes to mc_reg_address
This is a followup to:
drm/amd/powerplay: Fix buffer overflows with mc_reg_address

Rework *_set_mc_special_registers for the other architectures to
use the same logic as the first patch. This allows the last entry
of the array to be filled without an error message for example.
This doesn't fix any known problems, perhaps avoided by luck.

ci_set_mc_special_registers() error: buffer overflow 'table->mc_reg_address' 16 <= 16
tonga_set_mc_special_registers() error: buffer overflow 'table->mc_reg_address' 16 <= 16

Change the logic to check before access instead of after incrementing.
It's fine if j reaches max after we're done. This allows the last entry
of the array to be filled without an error message for example.
Changed some whitespace to clarify grouping.

f59548c882 drm/amdgpu:fix NULL pointer access during drv remove
NULL pointer is because original logic will step into
set_pde_pte() even after the gart.ptr is freed due to
there are twice gart_unbind() on all gart area.

also, there are other minor fixes:
1,since gart_init only create dummy page, the corresponding
gart_fini shouldn't do more like unbinding all GART, this is
unnecessary because in driver fini stage all GART unbinding
had already been done during each IP's SW_FINI (GMC's
SW_FINI is the last one called), so remove the step
for the GART unbinding in gart_fini().

2,gart_fini() is already invoked during each GMC IP's gart_fini
routine,e.g. gmc_vx_0_gart_fini(), so no need to manually
call it during ttm_fini().

3,amdgpu_gem_force_release() should be put ahead of
amdgpu_vm_manager_fini()
