Jesse.zhang@amd.com 574f4b5562 drm/amdgpu: optimize queue reset and stop logic for sdma_v5_0
This patch refactors the SDMA v5.0 queue reset and stop logic to improve
code readability, maintainability, and performance. The key changes include:

1. **Generalized `sdma_v5_0_gfx_stop` Function**:
   - Added an `inst_mask` parameter to allow stopping specific SDMA instances
     instead of all instances. This is useful for resetting individual queues.

2. **Simplified `sdma_v5_0_reset_queue` Function**:
   - Removed redundant loops and checks by directly using the `ring->me` field
     to identify the SDMA instance.
   - Reused the `sdma_v5_0_gfx_stop` function to stop the queue, reducing code
     duplication.

v1: The general coding style is to declare variables like "i" or "r" last. E.g. longest lines first and short lasts. (Chritian)
