Le Ma 2a47a2d90e drm/amdgpu: assign the doorbell index for sdma on non-AID0
Allocate new sdma doorbell index for the instances only on AID1 for now.

Todo: there's limitation that SDMA doorbell index on SDMA 4.4.2 needs to be
less than 0x1FF, so the tail part in _AMDGPU_VEGA20_DOORBELL_ASSIGNMENT is not
enough to store sdma doorbell range on maximum 4 AIDs if doorbell_range is 20.
So it looks better to create a new doorbell index assignment table for 4.4.2.

v2: change "(x << 1) + 2" to "(x + 1) << 1" for readability.
