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

Browse source

Align aldebaran with all other asics.  One HDP bit per
SDMA instance, aligned with firmware.  This is effectively
a revert of
commit a0f9f85466 ("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.
