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
