drm/amdgpu: use the same HDP flush registers for all nbio 7.4.x

Browse Source 
[ Upstream commit 912db6a58738e8be502838eb6a88f207ba356cd7 ]

Align aldebaran with all other asics.  One HDP bit per
SDMA instance, aligned with firmware.  This is effectively
a revert of
commit a0f9f8546668 ("drm/amdgpu/nbio7.4: don't use GPU_HDP_FLUSH bit 12").
On further discussions with the relevant hardware teams,
re-align the bits for SDMA.
