drm/amd: Add concept of running prepare_suspend() sequence for IP blocks
[ Upstream commit cb11ca3233aa3303dc11dca25977d2e7f24be00f ]
If any IP blocks allocate memory during their hw_fini() sequence
this can cause the suspend to fail under memory pressure. Introduce
a new phase that IP blocks can use to allocate memory before suspend
starts so that it can potentially be evicted into swap instead.
