Jesse.zhang@amd.com e4e6ae41cc drm/amdgpu: update SDMA sysfs reset mask in late_init
- Added `sdma_v4_4_2_update_reset_mask` function to update the reset mask.
- update the sysfs reset mask to the `late_init` stage to ensure that the SMU  initialization
     and capability setup are completed before checking the SDMA reset capability.
- For IP versions 9.4.3 and 9.4.4, enable per-queue reset if the MEC firmware version is at least 0xb0 and PMFW supports queue reset.
- Add a TODO comment for future support of per-queue reset for IP version 9.5.0.

This change ensures that per-queue reset is only enabled when the MEC and PMFW support it.

v2: fix ip version (9.5.4 -> 9.5.0)(Lijo)
