drm/amdgpu: use the same HDP flush registers for all nbio 2.3.x

Browse source

Align RDNA2.x with other asics.  One HDP bit per SDMA instance,
aligned with firmware.  This is effectively a revert of
commit 369b7d04ba ("drm/amdgpu/nbio2.3: don't use GPU_HDP_FLUSH bit 12").
On further discussions with the relevant hardware teams,
re-align the bits for SDMA.

Fixes: 369b7d04ba ("drm/amdgpu/nbio2.3: don't use GPU_HDP_FLUSH bit 12")
