[ Upstream commit 40a9592a26608e16f7545a068ea4165e1869f629 ]
On device initialization, a chunk of GTT memory is pre-allocated for HIQ and all SDMA queues mqd. The size of this allocation was wrong. The correct sdma engine number should be PCIe-optimized SDMA engine number plus xgmi SDMA engine number.
