HIP09 supports larger entries/contexts to improve the performance of bus or
exchange more information with the hardware. The capbilities changes from
HIP08 to HIP09 is as follows:
- CEQE: 4B -> 64B
- AEQE: 16B -> 64B
- CQE: 32B -> 64B
- QPC: 256B -> 512B

Previous discussions can be found at:
v1: https://patchwork.kernel.org/cover/11718143/

Changes since v1:
- Fix comments from Lang Cheng about redundant comments and type of
  reserved fields in structure of eqe.
- Rename some variables.
