From: "Jesse.zhang@xxxxxxx" <Jesse.zhang@xxxxxxx>
This patch updates the SDMA v4.4.2 software initialization to enable per-queue
reset support when the MEC firmware version is 0xb0 or higher and the PMFW
supports SDMA reset.
The following changes are included:
- Added a condition to check if the MEC firmware version is at least 0xb0 and if
the PMFW supports SDMA reset using `amdgpu_dpm_reset_sdma_is_supported`.
- If both conditions are met, the `AMDGPU_RESET_TYPE_PER_QUEUE` flag is set in
`adev->sdma.supported_reset`.
