drm/amdgpu: Enable GFX11 SDMA context empty interrupt

Browse source

Enable SDMA queue empty context switching. SDMA context switch due to
quantum programming no longer done here (as of sdma v6), so re-name
sdma_v6_0_ctx_switch_enable to sdma_v6_0_ctxempty_int_enable to reflect
this.

Also program SDMAx_QUEUEx_SCHEDULE_CNTL for context switch due to
quantum in KFD. Set to amdgpu_sdma_phase_quantum (defaults to 32 i.e.
3200us).
