[PATCH v3 6/9] drm/amdgpu: add new parameters in v11_struct

[Shashank Sharma <shashank.sharma@xxxxxxx>]

From: Arvind Yadav <arvind.yadav@xxxxxxx>

This patch:
- adds some new parameters defined for the gfx usermode queues
  use cases in the v11_mqd_struct.
- sets those parametes with the respective allocated gpu context
  space addresses.
