drm/amd/display: Remove unused mmhubbub_warmup field

mmhubbub_warmup is a field that was only read by the just removed
dc_stream_warmup_writeback() function.

Remove the field and it's initialisers.

It was only ever initialised to a single function value
(dcn30_mmhubbub_warmup) which is called explicitly elsewhere.
