sdm: Merge release fence after set power mode

On SetPowerMode() with retain pipes, DRM driver triggers the kick off
that enables MDP to read the previously queued buffer, Since the fence
created during SetPowerMode() is not merged with the previously queued
buffer, it may result in tearing. Hence get the release fence from
driver on SetPowerMode and propagate it to hwcomposer to merge it with
the previous release fence of all layer buffers to avoid tearing.
