drm/amdgpu: Adjust ras support check condition for special asic

[Why]:
     Amdgpu ras uses amdgpu_ras_is_supported to check whether
  the ras block supports the ras function. amdgpu_ras_is_supported
  uses .ras_enabled to determine whether the ras function of the
  block is enabled.
     But for special asic with mem ecc enabled but sram ecc not
  enabled, some ras blocks support poison mode but their ras function
  is not enabled on .ras_enabled, these ras blocks will run abnormally.

[How]:
    If the ras block is not supported on .ras_enabled but the asic
  supports poison mode and the ras block has ras configuration, it
  can be considered that the ras block supports ras function.
