drm/amdgpu: allocate entities on demand
Currently we pre-allocate entities and fences for all the HW IPs on context creation and some of which are might never be used. This patch tries to resolve entity/fences wastage by creating entity only when needed. v2: allocate memory for entity and fences together Signed-off-by: Nirmoy Das <nirmoy.das@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
