[PATCH 09/23] drm/amdkfd: Update packet manager for GFX9.4.3

[Alex Deucher]

From: Mukul Joshi <mukul.joshi at amd.com>

In GFX 9.4.3, there can be more than 8 SDMA engines.
As a result, extended_engine_sel and engine_sel fields
in MAP_QUEUES packet need to be updated to allow correct
mapping of SDMA queues to these SDMA engines.
