From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>

commit c5d3c9a093d353e7f38183a70df425f92e3c329d upstream.

Missing code for Yellow Carp to enable scatter gather - follows how
DCN21 support was added.

Tested that 8k framebuffer allocation and display can now succeed after
applying the patch.

v2: Add hookup in DM
