drm/amdgpu: Correct the loss of aca bank reg info
By polling, poll ACA bank count to ensure that valid
ACA bank reg info can be obtained
v2: add corresponding delay before send msg to SMU to query mca bank info
(Stanley)
v3: the loop cannot exit. (Thomas)
v4: remove amdgpu_aca_clear_bank_count. (Kevin)
v5: continuously inject ce. If a creation interruption
occurs at this time, bank reg info will be lost. (Thomas)
v5: each cycle is delayed by 100ms. (Tao)
