a7562ab35e drm/amd/display: remove GRPH_SURFACE_UPDATE_IMMEDIATE_EN field programming
This is causing asserts for dce 8 and 10 since they do not contain this
field. It is also unnecessary for later DCEs as it is left in it's
default state of 0

3379da831b drm/amd/display: Use dc_update_surfaces_for_stream for flip.
Today we use special interface for flip because of fear of cuncurency issues
over dc->current_ctx. This should be no longer an issue when flipping on
multiple CRTCs concurently since for fast update (as flip is) no new context
is created and the exsisitng is not destroyed. For full updates case when
removing or adding streams on once CRTC while flipping on another
Adding all current active CRTC's states to the atomic commit in
amdgpu_dm_atomic_check will garntee that any such full update commit
will wait for completion of any outstanding flip.

3273d3bfe5 drm/amd/display: Fix race.
Problem :
A race between two adjecent page flips makes the earlier one
to release an alocated frame buffer for the subsequent one -
since there are 2 frambuffer swapped back and forth between flips,
the 'new' fb of the later flip is actually the 'previous' fb for the earlier flip.
Fix:
Don't set fb->address = 0 in cleanup hook, this is unnecessery and
erases the newly cached adress that was set in prepare_fb of the second
flip.
