drm/amdgpu: use the same HDP flush registers for all nbio 2.3.x
Align RDNA2.x with other asics. One HDP bit per SDMA instance, aligned with firmware. This is effectively a revert of commit 369b7d04baf3 ("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: 369b7d04baf3 ("drm/amdgpu/nbio2.3: don't use GPU_HDP_FLUSH bit 12") Reviewed-by: Kent Russell <kent.russell@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
