drm/amdgpu: adjust the sequence to check soft reset

Browse Source 
1.Drop soft reset check when do should recover gpu check.
  (As it will skip gpu reset operation if some ip is hang but
   not support soft reset)
2.Check soft reset status before do soft reset when pre asic reset.
  a. If check soft reset return true, it means: some ip is hang and
     it also support soft reset, will try soft reset first.
  b. If check soft reset return false, it means:
       I.  All the ip are not hang, will skip gpu reset.
       II. Some ip is hang but not support soft reset, will skip soft
           reset and retry with full reset later.
