[ Upstream commit fe93b0927bc58cb1d64230f45744e527d9d8482c ]
Here are the corrections needed for the queue ring buffer size
calculation for the following cases:
- Remove the KIQ VM flush ring usage.
- Add the invalidate TLBs packet for gfx10 and gfx11 queue.
- There's no VM flush and PFP sync, so remove the gfx9 real
ring and compute ring buffer usage.
